\fBTcl_Backslash\fR(\fIsrc, countPtr\fR)
.SH ARGUMENTS
.AS char *countPtr out
.AP char *src in
Pointer to a string starting with a backslash.

.SH DESCRIPTION
.PP
The use of \fBTcl_Backslash\fR is deprecated in favor of
\fBTcl_UtfBackslash\fR.
.PP
This is a utility procedure provided for backwards compatibility with
non-internationalized Tcl extensions. It parses a backslash sequence and
returns the low byte of the Unicode character corresponding to the sequence.
\fBTcl_Backslash\fR modifies \fI*countPtr\fR to contain the number of
characters in the backslash sequence.
.PP
See the Tcl manual entry for information on the valid backslash sequences.
All of the sequences described in the Tcl manual entry are supported by
\fBTcl_Backslash\fR.
