SLPUNESCAPE(3SLP) Service Location Protocol Library Functions

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()

The following example decodes the representation for ",tag,":


char* pcOutBuf;
SLPError err;

err = SLPUnescape("\2c tag\2c", &pcOutbuf, SLP_TRUE);

ENVIRONMENT VARIABLES

SLP_CONF_FILE
When set, use this file for configuration.
