SLPUnescape(3SLP) Service Location Protocol Library FunctionsSLPUnescape(3SLP)NAMESLPUnescape - translate escaped characters into UTF-8
SYNOPSIS
#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 SLP‐
True, 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 allo‐
cated 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 char‐
acters.
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.
