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

NAME

SLPEscape - escapes SLP reserved characters

SYNOPSIS

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

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

DESCRIPTION

The SLPEscape() function processes the input string in pcInbuf and
escapes any SLP reserved characters. If the isTag parameter is
SLPTrue, it then looks for bad tag characters and signals an error if
any are found by returning the SLP_PARSE_ERROR code. 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. It must be freed using
SLPFree() when the memory is no longer needed.


isTag
When true, checks the input buffer 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: Converting Attribute Tags

The following example shows how to convert the attribute tag ,tag-
example, to on the wire format:


SLPError err;
char* escaped Chars;

err = SLPEscape(",tag-example,", &escapedChars, SLP_TRUE);

ENVIRONMENT VARIABLES
