.SH NAME
SLPUnescape \- translate escaped characters into UTF-8
.SH SYNOPSIS
.LP
.nf
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
.sp
.ne 2
.na
\fB\fIpcInBuf\fR\fR
.ad
.RS 13n
Pointer to the input buffer to process for escape characters.
.RE
.sp
.ne 2
.na
\fB\fIppcOutBuf\fR\fR
.ad
.RS 13n
Pointer to a pointer for the output buffer with the \fBSLP\fR reserved
characters escaped. Must be freed using \fBSLPFree\fR(3SLP) when the memory is
no longer needed.
.RE
.sp
.ne 2
.na
\fB\fIisTag\fR\fR
.ad
.RS 13n
When true, the input buffer is checked for bad tag characters.
.RE
.SH ERRORS
.sp
.LP
This function or its callback may return any \fBSLP\fR error code. See the
ERRORS section in \fBslp_api\fR(3SLP).
.SH EXAMPLES
