.SH NAME
SLPEscape \- escapes SLP reserved characters
.SH SYNOPSIS
.LP
.nf
cc [ \fIflag\fR... ] \fIfile\fR... \fB-lslp\fR [ \fIlibrary\fR... ]
#include <slp.h>

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

.SH DESCRIPTION
.sp
.LP
The \fBSLPEscape()\fR function processes the input string in \fIpcInbuf\fR and
escapes any \fBSLP\fR reserved characters.  If the \fIisTag\fR parameter is
\fBSLPTrue\fR, it then looks for bad tag characters and signals an error if any
are found by returning the \fBSLP_PARSE_ERROR\fR code.  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. It must be freed using \fBSLPFree()\fR when the memory is
no longer needed.
.RE

.sp
.ne 2
.na
\fB\fIisTag\fR\fR
.ad
.RS 13n
When true, checks the input buffer 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

\fBExample 1 \fRConverting Attribute Tags
.sp
.LP
The following example shows how to convert the attribute tag
\fB,tag-example,\fR to on the wire format:

.sp
.in +2
.nf
SLPError err;
char* escaped Chars;

err = SLPEscape(",tag-example,", &escapedChars, SLP_TRUE);
.fi
.in -2
