|
|
This is a utility procedure used by several of the Tcl
|
||
|
|
commands. It parses a backslash sequence and returns
|
||
|
|
the single character corresponding to the sequence.
|
||
|
|
\fBTcl_Backslash\fR modifies \fI*countPtr\fR to contain the number
|
||
|
|
of characters in the backslash sequence.

|
||
|
|
backslash sequences.
|
||
|
|
All of the sequences described in the Tcl
|
||
|
|
manual entry are supported by \fBTcl_Backslash\fR.
