SLPUnescape \- translate escaped characters into UTF-8
.SH SYNOPSIS

cc [ \fIflag\fR... ] \fIfile\fR... \fB-lslp\fR [ \fIlibrary\fR... ]
#include <slp.h>

\fBSLPError\fR \fBSLPUnescape\fR(\fBconst char *\fR\fIpcInBuf\fR, \fBchar**\fR \fIppcOutBuf\fR,
     \fBSLPBoolean\fR \fIisTag\fR);
.fi

.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.
.SH PARAMETERS
