.SH DESCRIPTION
.PP
These routines are used to create, modify, store, transfer, and retrieve
arbitrary binary data in Tcl values.  Specifically, data that can be
represented as a sequence of arbitrary byte values is supported.
This includes data read from binary channels, values created by the
\fBbinary\fR command, encrypted data, or other information representable as

Points to a variable that will have the value from a key/value pair
placed within it.  For \fBTcl_DictObjFirst\fR and
\fBTcl_DictObjNext\fR, this may be NULL to indicate that the caller is
not interested in the value.
.AP "Tcl_Size \&| int" *sizePtr out
Points to a variable that will have the number of key/value pairs
contained within the dictionary placed within it.
May be (Tcl_Size *)NULL when not used. If it points to a variable which
type is not \fBTcl_Size\fR, a compiler warning will be generated.
If your extensions is compiled with -DTCL_8_API, this function will return
NULL for dictionaries larger than INT_MAX (which should
trigger proper error-handling), otherwise expect it to crash.
.AP Tcl_DictSearch *searchPtr in/out
Pointer to record to use to keep track of progress in enumerating all
key/value pairs in a dictionary.  The contents of the record will be
initialized by the call to \fBTcl_DictObjFirst\fR.  If the enumerating
is to be terminated before all values in the dictionary have been
returned, the search record \fImust\fR be passed to
\fBTcl_DictObjDone\fR to enable the internal locks to be released.

If non-NULL, filled with the number of elements in the split path.
Filled with the number of elements in the split path.
May be (Tcl_Size *)NULL when not used. If it points to a variable which
type is not \fBTcl_Size\fR, a compiler warning will be generated.
If your extensions is compiled with -DTCL_8_API, this function will return
NULL for paths having more than INT_MAX elements (which should
trigger proper error-handling), otherwise expect it to crash.
.AP Tcl_Obj *basePtr in
The base path on to which to join the given elements. May be NULL.
.AP Tcl_Size objc in
The number of elements in \fIobjv\fR.

this points to the Tcl value that will be converted to a list value
containing the \fIobjc\fR elements of the array referenced by \fIobjv\fR.
.AP "Tcl_Size \&| int" *objcPtr in
Points to location where \fBTcl_ListObjGetElements\fR
stores the number of element values in \fIlistPtr\fR.
May be (Tcl_Size *)NULL when not used. If it points to a variable which
type is not \fBTcl_Size\fR, a compiler warning will be generated.
If your extensions is compiled with -DTCL_8_API, this function will return

will insert into a new list value,
and \fBTcl_ListObjReplace\fR will insert into \fIlistPtr\fR.
For \fBTcl_SetListObj\fR,
the number of Tcl values to insert into \fIobjPtr\fR.
.AP "Tcl_Obj *const" objv[] in
An array of pointers to values.
\fBTcl_NewListObj\fR will insert these values into a new list value
and \fBTcl_ListObjReplace\fR will insert them into an existing \fIlistPtr\fR.
Each value will become a separate list element.
.AP "Tcl_Size \&| int" *lengthPtr out
Points to location where \fBTcl_ListObjLength\fR
stores the length of the list.
May be (Tcl_Size *)NULL when not used. If it points to a variable which
type is not \fBTcl_Size\fR, a compiler warning will be generated.
If your extensions is compiled with -DTCL_8_API, this function will return
TCL_ERROR for lists with more than INT_MAX elements (which should
trigger proper error-handling), otherwise expect it to crash.

The first element has index 0.
.AP Tcl_Obj **objPtrPtr out
Points to place where \fBTcl_ListObjIndex\fR is to store
a pointer to the resulting list element value.

will attempt to convert it to one; if the conversion fails, it returns
\fBTCL_ERROR\fR and leaves an error message in the interpreter's result
value if \fIinterp\fR is not NULL.
Otherwise it returns \fBTCL_OK\fR after storing the count and array pointer.
.PP
\fBTcl_ListObjLength\fR returns the number of elements in the list value
referenced by \fIlistPtr\fR.
It returns this count by storing a value in the address \fIlengthPtr\fR.
If \fIlengthPtr\fR points to a variable of type \fBint\fR and the list
contains more than 2**31 elements, the function returns \fBTCL_ERROR\fR.
If the value is not already a list value,
\fBTcl_ListObjLength\fR will attempt to convert it to one;
if the conversion fails, it returns \fBTCL_ERROR\fR
and leaves an error message in the interpreter's result value
if \fIinterp\fR is not NULL.
Otherwise it returns \fBTCL_OK\fR after storing the list's length.

modified to hold number of arguments left in the unprocessed argument list
stored in \fIremObjv\fR.
May be (Tcl_Size *)NULL when not used. If it points to a variable which
type is not \fBTcl_Size\fR, a compiler warning will be generated.
If your extensions is compiled with -DTCL_8_API, this function will return
NULL for argument lists with more than INT_MAX elements (which should

.AP "Tcl_Obj *const" *objv in
The array of arguments to be parsed.
.AP Tcl_Obj ***remObjv out
Pointer to a variable that will hold the array of unprocessed arguments.
Should be NULL if no return of unprocessed arguments is required. If
\fIobjcPtr\fR is updated to a non-zero value, the array returned through this
must be deallocated using \fBTcl_Free\fR.

.SH NAME
const \- create and initialize a constant
.SH SYNOPSIS
\fBconst \fIvarName value\fR
.BE
.SH DESCRIPTION
.PP
This command is normally used within a procedure body (or method body,
or lambda term) to create a constant within that procedure, or within a
\fBnamespace eval\fR body to create a constant within that namespace.
The constant is an unmodifiable variable, called \fIvarName\fR, that is
initialized with \fIvalue\fR.
The result of \fBconst\fR is always the empty string on success.
.PP
If a variable \fIvarName\fR does not exist, it is created with its value set
to \fIvalue\fR and marked as a constant; this means that no other command
(e.g., \fBset\fR, \fBappend\fR, \fBincr\fR, \fBunset\fR)
may modify or remove the variable; variables are checked for whether they
are constants before any traces are called.
If a variable \fIvarName\fR already exists, it is an error unless that
variable is marked as a constant (in which case \fBconst\fR is a no-op).
.PP
The \fIvarName\fR may not be a qualified name or reference an element of an
array by any means. If the variable exists and is an array, that is an error.
.PP
Constants are normally only removed by their containing procedure exiting or
their namespace being deleted.
.SH EXAMPLES
.PP
Create a constant in a procedure:
.PP

proc foo {a b} {
    \fBconst\fR BAR 12345
    return [expr {$a + $b + $BAR}]

        variable FOO_MATCHER
        regexp -all $FOO_MATCHER $str
    }

    proc findFooIndices str {
        variable FOO_MATCHER
        regexp -all -indices $FOO_MATCHER $str
    }
}

    set result {}
    for {set i 0} {$i < $n} {incr i} {

fcopy \- Copy data from one channel to another
.SH SYNOPSIS
\fBfcopy \fIinputChan\fR \fIoutputChan\fR ?\fB\-size \fIsize\fR? ?\fB\-command \fIcallback\fR?
.BE

.SH DESCRIPTION
.PP
Reads characters from \fIinputChan\fR and writes them to \fIoutputChan\fR until
The \fBfcopy\fR command copies data from one I/O channel, \fIinchan\fR to another I/O channel, \fIoutchan\fR.
all characters are copied, blocking until the copy is complete and returning
the number of characters copied.  Leverages internal buffers to avoid extra
copies and to avoid buffering too much data in main memory when copying large
files to slow destinations like network sockets.
The \fBfcopy\fR command leverages the buffering in the Tcl I/O system to
avoid extra copies and to avoid buffering too much data in
main memory when copying large files to destinations like
network sockets.
.
.SS "DATA QUANTITY"
All data until \fIEOF\fR is copied.
In addition, the quantity of copied data may be specified by the option \fB-size\fR.
The given size is in bytes, if the input channel is in binary mode.
Otherwise, it is in characters.
.PP
Depreciated feature: the transfer is treated as a binary transfer, if the encoding
profile is set to
.QW tcl8
and the input encoding matches the output encoding.
In this case, eventual encoding errors are not handled.
An eventually given size is in bytes in this case.
.
.SS "BLOCKING OPERATION MODE"
Without the \fB\-command\fR option, \fBfcopy\fR blocks until the copy is complete
\fB\-size\fR limits the number of characters copied.
and returns the number of bytes or characters (using the same rules as
.PP
\fB\-command\fR makes \fBfcopy\fR return immediately, work in the background,
and call \fIcallback\fR when the copy completes, providing as an additional
argument the number of characters written to \fIoutputChan\fR.  If an error
occurres during the background copy, another argument provides the message for
the error.  \fIinputChan\fR and \fIoutputChan\fR are automatically configured
for non-blocking mode if needed.  Background copying only works correctly if
events are being processed e.g. via \fBvwait\fR or Tk.
for the \fB\-size\fR option) written to \fIoutchan\fR.
.
.SS "BACKGROUND OPERATION MODE"
The \fB\-command\fR argument makes \fBfcopy\fR work in the background.
In this case it returns immediately and the \fIcallback\fR is invoked
later when the copy completes.
The \fIcallback\fR is called with
one or two additional
arguments that indicates how many bytes were written to \fIoutchan\fR.
If an error occurred during the background copy, the second argument is the
error string associated with the error.
With a background copy,
it is not necessary to put \fIinchan\fR or \fIoutchan\fR into
non-blocking mode; the \fBfcopy\fR command takes care of that automatically.
However, it is necessary to enter the event loop by using
the \fBvwait\fR command or by using Tk.
.PP
You are not allowed to do other input operations with \fIinchan\fR, or
During a background copy no other read operation may be performed on
output operations with \fIoutchan\fR, during a background
\fIinputChan\fR, and no other write operation may be performed on
\fIoutputChan\fR.  However, write operations may by performed on
\fIinputChan\fR and read operations may be performed on \fIoutputChan\fR, as
exhibited by the bidirectional copy example below.
\fBfcopy\fR. The converse is entirely legitimate, as exhibited by the
bidirectional fcopy example below.
.PP
If either \fIinchan\fR or \fIoutchan\fR get closed
If either \fIinputChan\fR or \fIoutputChan\fR is closed while the copy is in
progress, copying ceases and \fBno\fR callback is made.  If \fIinputChan\fR is
closed all data already queued is written to \fIoutputChan\fR.
while the copy is in progress, the current copy is stopped
and the command callback is \fInot\fR made.
If \fIinchan\fR is closed,
then all data already queued for \fIoutchan\fR is written out.
.PP
There should be no event handler established for \fIinputChan\fR  because it
may become readable during a background copy.  An attempt to read or write from

You should turn off any \fBfileevent\fR handlers during a background
copy so those handlers do not interfere with the copy.
Any wrong-sided I/O attempted (by a \fBfileevent\fR handler or otherwise) will get a
in a
.QW "channel busy"
error.
.
.SS "CHANNEL TRANSLATION OPTIONS"
\fBFcopy\fR translates end-of-line sequences in \fIinchan\fR and \fIoutchan\fR
according to the \fB\-translation\fR option
for these channels.
See the manual entry for \fBfconfigure\fR for details on the
\fB\-translation\fR option.
The translations mean that the number of bytes read from \fIinchan\fR
can be different than the number of bytes written to \fIoutchan\fR.
Only the number of bytes written to \fIoutchan\fR is reported,
either as the return value of a synchronous \fBfcopy\fR or
as the argument to the callback for an asynchronous \fBfcopy\fR.
.SS "CHANNEL ENCODING OPTIONS"
\fBFcopy\fR obeys the encodings, profiles and character translations configured
for the channels. This
means that the incoming characters are converted internally first
UTF-8 and then into the encoding of the channel \fBfcopy\fR writes
to. See the manual entry for \fBfconfigure\fR for details on the
\fB\-encoding\fR and \fB\-profile\fR options. No conversion is
done if both channels are
set to encoding
.QW binary
and have matching translations. If only the output channel is set to encoding
.QW binary
the system will write the internal UTF-8 representation of the incoming
characters. If only the input channel is set to encoding
.QW binary
the system will assume that the incoming
bytes are valid UTF-8 characters and convert them according to the
output encoding. The behaviour of the system for bytes which are not
valid UTF-8 characters is undefined in this case.
.PP
\fBFcopy\fR may throw encoding errors (error code \fBEILSEQ\fR), if input or output
channel is configured to the
.QW strict
encoding profile.
.PP
If an encoding error arises on the input channel, any data before the error byte is
written to the output channel. The input file pointer is located just before the
values causing the encoding error.
Error inspection or recovery is possible by changing the encoding parameters and
invoking a file command (\fBread\fR, \fBfcopy\fR).
.PP
If an encoding error arises on the output channel, the errorneous data is lost.
To make the difference between the input error case and the output error case, only the
error message may be inspected (read or write), as both throw the error code \fIEILSEQ\fR.
.SH EXAMPLES
.PP
The first example transfers the contents of one channel exactly to
another. Note that when copying one file to another, it is better to
use \fBfile copy\fR which also copies file metadata (e.g. the file
access permissions) where possible.
.PP

    incr total $bytes
    if {([string length $error] != 0) || [eof $in]} {
        set done $total
        close $in
        close $out
    } else {
        \fBfcopy\fR $in $out -size $chunk \e
            -command [list CopyMore $in $out $chunk]
                -command [list CopyMore $in $out $chunk]

.CE
.PP
The fourth example starts an asynchronous, bidirectional fcopy between
two sockets. Those could also be pipes from two [open "|hal 9000" r+]
(though their conversation would remain secret to the script, since
all four fileevent slots are busy).

then \fBhttp\fR will set a new value in order to make optional

Iff argument \fIendToEndProxy\fR is supplied and is boolean \fItrue\fR,
then when \fBhttp::geturl\fR accesses a server via a proxy, it will
open a channel by sending a CONNECT request to the proxy, and it will
