\fBincr x\fR
.CE
.PP
The \fBincr\fR command first gets an integer from \fIx\fR's value
by calling \fBTcl_GetIntFromObj\fR.
This procedure checks whether the value is already an integer value.
Since it is not, it converts the value
by setting the value's \fIinternalRep.longValue\fR member
by setting the value's internal representation
to the integer \fB123\fR
and setting the value's \fItypePtr\fR
to point to the integer Tcl_ObjType structure.
Both representations are now valid.
\fBincr\fR increments the value's integer internal representation
then invalidates its string representation
(by calling \fBTcl_InvalidateStringRep\fR)

value may then be passed back to one of \fBTcl_RestoreInterpState\fR
or \fBTcl_DiscardInterpState\fR, depending on whether the interp
state is to be restored.  So long as one of the latter two routines
is called, Tcl will take care of memory management.
.PP
The second triplet stores the snapshot of only the interpreter
result (not its complete state) in memory allocated by the caller.
These routines are passed a pointer to a \fBTcl_SavedResult\fR structure
These routines are passed a pointer to \fBTcl_SavedResult\fR
that is used to store enough information to restore the interpreter result.
This structure can be allocated on the stack of the calling
\fBTcl_SavedResult\fR can be allocated on the stack of the calling
procedure.  These routines do not save the state of any error
information in the interpreter (e.g. the \fB\-errorcode\fR or
\fB\-errorinfo\fR return options, when an error is in progress).
.PP
Because the routines \fBTcl_SaveInterpState\fR,
\fBTcl_RestoreInterpState\fR, and \fBTcl_DiscardInterpState\fR perform
a superset of the functions provided by the other routines,

\fBTcl_UtfToLower\fR(\fIstr\fR)
.sp
int
\fBTcl_UtfToTitle\fR(\fIstr\fR)
.SH ARGUMENTS
.AS char *str in/out
.AP int ch in
The Tcl_UniChar to be converted.
The Unicode character to be converted.
.AP char *str in/out
Pointer to UTF-8 string to be converted in place.

.SH DESCRIPTION
.PP
The first three routines convert the case of individual Unicode characters:

\fBTcl_UniCharIsUpper\fR(\fIch\fR)
.sp
int
\fBTcl_UniCharIsWordChar\fR(\fIch\fR)
.SH ARGUMENTS
.AS int ch
.AP int ch in
The Tcl_UniChar to be examined.
The Unicode character to be examined.
.BE

.SH DESCRIPTION
.PP
All of the routines described examine Tcl_UniChars and return a
All of the routines described examine Unicode characters and return a
boolean value. A non-zero return value means that the character does
belong to the character class associated with the called routine. The
rest of this document just describes the character classes associated
with the various routines.
.PP
Note: A Tcl_UniChar is a Unicode character represented as an unsigned,
fixed-size quantity.

.SH "CHARACTER CLASSES"
.PP
\fBTcl_UniCharIsAlnum\fR tests if the character is an alphanumeric Unicode character.
.PP
\fBTcl_UniCharIsAlpha\fR tests if the character is an alphabetic Unicode character.
.PP

\fBTcl_UtfBackslash\fR(\fIsrc, readPtr, dst\fR)
.SH ARGUMENTS
.AS "const Tcl_UniChar" *uniPattern in/out
.AP char *buf out
Buffer in which the UTF-8 representation of the Tcl_UniChar is stored.  At most
\fBTCL_UTF_MAX\fR bytes are stored in the buffer.
.AP int ch in
The Tcl_UniChar to be converted or examined.
The Unicode character to be converted or examined.
.AP Tcl_UniChar *chPtr out
Filled with the Tcl_UniChar represented by the head of the UTF-8 string.
.AP "const char" *src in
Pointer to a UTF-8 string.
