(const char *pcInBuf
, char** ppcOutBuf
, SLPBoolean isTag
function processes the input string in pcInbuf
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
This buffer should be deallocated using SLPFree(3SLP)
when the memory is
no longer needed.
Pointer to the input buffer to process for escape
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
This function or its callback may return any SLP
error code. See the
ERRORS section in slp_api(3SLP)
Example 1: Using SLPUnescape()
The following example decodes the representation for ",tag,"
err = SLPUnescape("\2c tag\2c", &pcOutbuf, SLP_TRUE);
