SLPUNESCAPE(3SLP) Service Location Protocol Library Functions SLPUNESCAPE(3SLP)


NAME


SLPUnescape - translate escaped characters into UTF-8

SYNOPSIS


cc [ flag... ] file... -lslp [ library... ]
#include <slp.h>

SLPError SLPUnescape(const char *pcInBuf, char** ppcOutBuf,
SLPBoolean isTag);


DESCRIPTION


The SLPUnescape() function processes the input string in pcInbuf and
unescapes any SLP reserved characters. If the isTag parameter is
SLPTrue, then look for bad tag characters and signal an error if any are
found with the SLP_PARSE_ERROR code. No transformation is performed if
the input string is an opaque. The results are put into a buffer
allocated by the API library and returned in the ppcOutBuf parameter.
This buffer should be deallocated using SLPFree(3SLP) when the memory is
no longer needed.

PARAMETERS


pcInBuf
Pointer to the input buffer to process for escape
characters.


ppcOutBuf
Pointer to a pointer for the output buffer with the SLP
reserved characters escaped. Must be freed using
SLPFree(3SLP) when the memory is no longer needed.


isTag
When true, the input buffer is checked for bad tag
characters.


ERRORS


This function or its callback may return any SLP error code. See the
ERRORS section in slp_api(3SLP).

EXAMPLES


Example 1: Using SLPUnescape()

ENVIRONMENT VARIABLES
