\fBSLPError\fR \fBSLPUnescape\fR(\fBconst char *\fR\fIpcInBuf\fR, \fBchar**\fR \fIppcOutBuf\fR,

.SH DESCRIPTION
.sp
.LP
The \fBSLPUnescape()\fR function processes the input string in \fIpcInbuf\fR and unescapes any \fBSLP\fR reserved characters.  If the \fIisTag\fR parameter is \fBSLPTrue\fR, then look for bad tag characters and signal an error if any are found with the \fBSLP_PARSE_ERROR\fR code.  No transformation is performed if the input string is an opaque.  The results are put into a buffer allocated by the \fBAPI\fR library and returned in the \fIppcOutBuf\fR parameter.  This buffer should be deallocated using \fBSLPFree\fR(3SLP) when the memory is no longer needed.
