.SH DESCRIPTION
.PP
These procedures provide a platform and compiler independent interface
for memory allocation.  Programs that need to transfer ownership of
memory blocks between Tcl and other modules should use these routines

as macros.  Normally, they are synonyms for the corresponding
procedures documented on this page.  When Tcl and all modules
calling Tcl are compiled with \fBTCL_MEM_DEBUG\fR defined, however,
these macros are redefined to be special debugging versions
of these procedures.  To support Tcl's memory debugging within a
module, use the macros rather than direct calls to \fBTcl_Alloc\fR, etc.

\fBTcl_GetMemoryInfo\fR appends a list-of-lists of memory stats to the
provided DString. This function cannot be used in stub-enabled extensions,
and it is only available if Tcl is compiled with the threaded memory allocator.

.SH DESCRIPTION
.PP
These procedures may be used to manipulate the current working
directory for the application.  They provide C\-level access to
the same functionality as the Tcl \fBpwd\fR command.
.PP
\fBTcl_GetCwd\fR returns a pointer to a string specifying the current
directory, or NULL if the current directory could not be determined.
If NULL is returned, an error message is left in the \fIinterp\fR's result.
Storage for the result string is allocated in bufferPtr; the caller
must call \fBTcl_DStringFree()\fR when the result is no longer needed.
The format of the path is UTF\-8.
.PP
\fBTcl_Chdir\fR changes the applications current working directory to
the value specified in \fIdirName\fR.  The format of the passed in string
must be UTF\-8.  The function returns -1 on error or 0 on success.

.BE
.SH DESCRIPTION
.PP
\fBTcl_Main\fR can serve as the main program for Tcl-based shell
applications.  A
.QW "shell application"
is a program

\fBTcl_UtfToUniChar\fR reads one UTF-8 character starting at \fIsrc\fR
and stores it as a Tcl_UniChar in \fI*chPtr\fR.  The return value is the
number of bytes read from \fIsrc\fR.  The caller must ensure that the
source buffer is long enough such that this routine does not run off the
end and dereference non-existent or random memory; if the source buffer
is known to be null-terminated, this will not happen.  If the input is
not in proper UTF-8 format, \fBTcl_UtfToUniChar\fR will store the first
byte of \fIsrc\fR in \fI*chPtr\fR as a Tcl_UniChar between 0x80 and
0xFF and return 1.
.PP
\fBTcl_UniCharToUtfDString\fR converts the given Unicode string
to UTF-8, storing the result in a previously initialized \fBTcl_DString\fR.
You must specify \fIuniLength\fR, the length of the given Unicode string.
The return value is a pointer to the UTF-8 representation of the
Unicode string.  Storage for the return value is appended to the
end of the \fBTcl_DString\fR.

\fBTcl_UtfNcasecmp\fR corresponds to \fBstrncasecmp\fR for UTF-8
strings.  It is similar to \fBTcl_UtfNcmp\fR except comparisons ignore
differences in case when comparing upper, lower or title case
characters.
.PP
\fBTcl_UtfCharComplete\fR returns 1 if the source UTF-8 string \fIsrc\fR
of \fIlength\fR bytes is long enough to be decoded by
\fBTcl_UtfToUniChar\fR/\fBTcl_UtfNext\fR, or 0 otherwise.  This function
does not guarantee that the UTF-8 string is properly formed.  This routine
is used by procedures that are operating on a byte at a time and need to
know if a full Tcl_UniChar has been seen.
.PP
\fBTcl_NumUtfChars\fR corresponds to \fBstrlen\fR for UTF-8 strings.  It
returns the number of Tcl_UniChars that are represented by the UTF-8 string
\fIsrc\fR.  The length of the source string is \fIlength\fR bytes.  If the
length is negative, all bytes up to the first null byte are used.
.PP
\fBTcl_UtfFindFirst\fR corresponds to \fBstrchr\fR for UTF-8 strings.  It
returns a pointer to the first occurrence of the Tcl_UniChar \fIch\fR
in the null-terminated UTF-8 string \fIsrc\fR.  The null terminator is
considered part of the UTF-8 string.
.PP
\fBTcl_UtfFindLast\fR corresponds to \fBstrrchr\fR for UTF-8 strings.  It
returns a pointer to the last occurrence of the Tcl_UniChar \fIch\fR
in the null-terminated UTF-8 string \fIsrc\fR.  The null terminator is
considered part of the UTF-8 string.
.PP
Given \fIsrc\fR, a pointer to some location in a UTF-8 string,
\fBTcl_UtfNext\fR returns a pointer to the next UTF-8 character in the
string.  The caller must not ask for the next character after the last
character in the string if the string is not terminated by a null
character. \fBTcl_UtfCharComplete\fR can be used in that case to
make sure enough bytes are available before calling \fBTcl_UtfNext\fR.
.PP
\fBTcl_UtfPrev\fR is used to step backward through but not beyond the
UTF-8 string that begins at \fIstart\fR.  If the UTF-8 string is made
up entirely of complete and well-formed characters, and \fIsrc\fR points
to the lead byte of one of those characters (or to the location one byte
past the end of the string), then repeated calls of \fBTcl_UtfPrev\fR will
return pointers to the lead bytes of each character in the string, one

hours, minutes, and seconds (if six digits are present) from
UTC.  The plus sign denotes a sign east of Greenwich;
the minus sign one west of Greenwich.
.PP
A time zone string conforming to the Posix specification of the \fBTZ\fR
environment variable will be recognized.  The specification
may be found at
\fIhttps://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap08.html\fR.
.PP
If the Posix time zone string contains a DST (Daylight Savings Time)
part, but doesn't contain a rule stating when DST starts or ends,
then default rules are used. For Timezones with an offset between 0
and +12, the current European/Russian rules are used, otherwise the
current US rules are used. In Europe (offset +0 to +2) the switch
to summertime is done each last Sunday in March at 1:00 GMT, and

rules change again.

Any other time zone string is processed by prefixing a colon and attempting
to use it as a location name, as above.

This command treats its arguments as the specification
of one or more subprocesses to execute.
The arguments take the form of a standard shell pipeline
where each \fIarg\fR becomes one word of a command, and
each distinct command becomes a subprocess.
The result of the command is the standard output of the final subprocess in
the pipeline, interpreted using the system \fBencoding\fR; to use any other
encoding (especially including binary data), the pipeline must be
\fBopen\fRed, configured and read explicitly.

If the initial arguments to \fBexec\fR start with \fB\-\fR then
they are treated as command-line switches and are not part
of the pipeline specification.  The following switches are

\fB\-owner\fR gets or sets the user name of the owner of the file. The
command returns the owner name, but the numerical id can be passed when
setting the owner. \fB\-permissions\fR retrieves or sets a file's
access permissions, using octal notation by default. This option also
provides limited support for setting permissions using the symbolic

notation accepted by the \fBchmod\fR command, following the form
[\fBugo\fR]?[[\fB+-=\fR][\fBrwxst\fR]\fB,\fR[...]]. Multiple permission
specifications may be given, separated by commas. E.g., \fBu+s,go-rw\fR
would set the setuid bit for a file's owner as well as remove read and
write permission for the file's group and other users. An
\fBls\fR-style string of the form \fBrwxrwxrwx\fR is also accepted but
must always be 9 characters long. E.g., \fBrwxr-xr-t\fR is equivalent
to \fB01755\fR. On versions of Unix supporting file flags,

.SH DESCRIPTION
.PP
This command loads binary code from a file into the
application's address space and calls an initialization procedure
in the library to incorporate it into an interpreter.  \fIfileName\fR
is the name of the file containing the code;  its exact form varies
from system to system but on most systems it is a shared library,
such as a \fB.so\fR file under Solaris or a DLL under Windows.

\fIprefix\fR is used to compute the name of an initialization procedure.
\fIinterp\fR is the path name of the interpreter into which to load
the library (see the \fBinterp\fR manual entry for details);
if \fIinterp\fR is omitted, it defaults to the
interpreter in which the \fBload\fR command was invoked.
.PP
Once the file has been loaded into the application's address space,
one of two initialization procedures will be invoked in the new code.
Typically the initialization procedure will add new commands to a
Tcl interpreter.
The name of the initialization procedure is determined by
\fIprefix\fR and whether or not the target interpreter
is a safe one.  For normal interpreters the name of the initialization
procedure will have the form \fIpfx\fB_Init\fR, where \fIpfx\fR
is the same as \fIprefix\fR except that the first letter is
converted to upper case and all other letters
are converted to lower case.  For example, if \fIprefix\fR is
\fBfoo\fR or \fBFOo\fR, the initialization procedure's name will
be \fBFoo_Init\fR.
.PP
If the target interpreter is a safe interpreter, then the name
of the initialization procedure will be \fIpfx\fB_SafeInit\fR
instead of \fIpfx\fB_Init\fR.
The \fIpfx\fB_SafeInit\fR function should be written carefully, so that it
initializes the safe interpreter only with partial functionality provided
by the library that is safe for use by untrusted code. For more information
on Safe\-Tcl, see the \fBsafe\fR manual entry.
.PP
The initialization procedure must match the following prototype:
.PP
.CS
typedef int \fBTcl_PackageInitProc\fR(
        Tcl_Interp *\fIinterp\fR);
.CE
.PP
The \fIinterp\fR argument identifies the interpreter in which the
library is to be loaded.  The initialization procedure must return
\fBTCL_OK\fR or \fBTCL_ERROR\fR to indicate whether or not it completed
successfully;  in the event of an error it should set the interpreter's result
to point to an error message.  The result of the \fBload\fR command
will be the result returned by the initialization procedure.
.PP
The actual loading of a file will only be done once for each \fIfileName\fR
in an application.  If a given \fIfileName\fR is loaded into multiple
interpreters, then the first \fBload\fR will load the code and
call the initialization procedure;  subsequent \fBload\fRs will
call the initialization procedure without loading the code again.
For Tcl versions lower than 8.5, it is not possible to unload or reload a
library. From version 8.5 however, the \fBunload\fR command allows the unloading
of libraries loaded with \fBload\fR, for libraries that are aware of the
Tcl's unloading mechanism.
.PP
The \fBload\fR command also supports libraries that are statically
linked with the application, if those libraries have been registered
by calling the \fBTcl_StaticPackage\fR procedure.
If \fIfileName\fR is an empty string, then \fIprefix\fR must
be specified.
.PP
If \fIprefix\fR is omitted or specified as an empty string,
Tcl tries to guess the prefix. This may be done differently on
different platforms. The default guess, which is used on most
UNIX platforms, is to take the last element of
\fIfileName\fR, strip off the first three characters if they
are \fBlib\fR, and use any following alphabetic and
underline characters, converted to titlecase as the prefix.
For example, the command \fBload libxyz4.2.so\fR uses the prefix
\fBXyz\fR and the command \fBload bin/last.so {}\fR uses the
prefix \fBLast\fR.
.PP
If \fIfileName\fR is an empty string, then \fIprefix\fR must
be specified.
The \fBload\fR command first searches for a statically loaded library
(one that has been registered by calling the \fBTcl_StaticPackage\fR
procedure) by that name; if one is found, it is used.
Otherwise, the \fBload\fR command searches for a dynamically loaded
library by that name, and uses it if it is found.  If several
different files have been \fBload\fRed with different versions of
the library, Tcl picks the file that was loaded first.
.PP
If \fB\-global\fR is specified preceding the filename, all symbols
found in the shared library are exported for global use by other
libraries. The option \fB\-lazy\fR delays the actual loading of
symbols until their first actual use. The options may be abbreviated.
The option \fB\-\-\fR indicates the end of the options, and should
be used if you wish to use a filename which starts with \fB\-\fR
and you provide a prefix to the \fBload\fR command.
.PP
On platforms which do not support the \fB\-global\fR or \fB\-lazy\fR
options, the options still exist but have no effect. Note that use
of the \fB\-global\fR or \fB\-lazy\fR option may lead to crashes
in your application later (in case of symbol conflicts resp. missing
symbols), which cannot be detected during the \fBload\fR. So, only
use this when you know what you are doing, you will not get a nice

The list is ordered from most specific to least
preference.  The list is derived from the current
locale set in msgcat by \fB::msgcat::mclocale\fR, and

.PP
This command tries to unload shared libraries previously loaded
with \fBload\fR from the application's address space.  \fIfileName\fR
is the name of the file containing the library file to be unload;  it
must be the same as the filename provided to \fBload\fR for
loading the library.
The \fIprefix\fR argument is the prefix (as
determined by or passed to \fBload\fR), and is used to
compute the name of the unload procedure; if not supplied, it is
computed from \fIfileName\fR in the same manner as \fBload\fR.
The \fIinterp\fR argument is the path name of the interpreter from
which to unload the package (see the \fBinterp\fR manual entry for
details); if \fIinterp\fR is omitted, it defaults to the
interpreter in which the \fBunload\fR command was invoked.

call on the file), these counters track how many interpreters use the library.
Each subsequent call to \fBload\fR after the first simply increments the
proper reference count.
.PP
\fBunload\fR works in the opposite direction. As a first step, \fBunload\fR
will check whether the library is unloadable: an unloadable library exports
a special unload procedure. The name of the unload procedure is determined by
\fIprefix\fR and whether or not the target interpreter
is a safe one.  For normal interpreters the name of the initialization
procedure will have the form \fIpfx\fB_Unload\fR, where \fIpfx\fR
is the same as \fIprefix\fR except that the first letter is
converted to upper case and all other letters
are converted to lower case.  For example, if \fIprefix\fR is
\fBfoo\fR or \fBFOo\fR, the initialization procedure's name will
be \fBFoo_Unload\fR.
If the target interpreter is a safe interpreter, then the name
of the initialization procedure will be \fIpkg\fB_SafeUnload\fR
instead of \fIpkg\fB_Unload\fR.
.PP
If \fBunload\fR determines that a library is not unloadable (or unload

library is used only by the target interpreter and the library will be
detached from the application as soon as the unload procedure returns,
the \fIflags\fR argument will be set to \fBTCL_UNLOAD_DETACH_FROM_PROCESS\fR.
