SLPParseSrvURL - parse service URL
cc [ flag... ] file... -lslp [ library... ]
#include <slp.h>
SLPError SLPParseSrvURL(const char *pcSrvURL, SLPSrvURL** ppSrvURL);
The SLPParseSrvURL() routine parses the URL passed in as the
argument into a service URL structure and returns it in the
ppSrvURL pointer. If a parser error occurs, returns
SLP_PARSE_ERROR. The structure returned in ppSrvURL should be
freed with SLPFree(). If the URL has no service part, the
s_pcSrvPart string is the empty string, "", that is, it is not
NULL. If pcSrvURL is not a service: URL, then the s_pcSrvType
field in the returned data structure is the URL's scheme,
which might not be the same as the service type under which the URL
was registered. If the transport is IP, the s_pcNetFamily field
is the empty string.
If no error occurs, the return value is the SLP_OK. Otherwise, if
an error occurs, one of the SLPError codes is returned.
pcSrvURL
A pointer to a character buffer containing the null
terminated URL string to parse. It is destructively
modified to produce the output structure. It may not be
NULL.
ppSrvURL
A pointer to a ponter for the SLPSrvURL structure to
receive the parsed URL. It may not be NULL.
This function or its callback may return any SLP error code. See the
ERRORS section in slp_api(3SLP).
The following example uses the SLPParseSrvURL() function to parse the
service URL service:printer:lpr://serv/queue1:
SLPSrvURL* surl;
SLPError err;
err = SLPParseSrvURL("service:printer:lpr://serv/queue1", &surl);

NAME
SLPParseSrvURL - parse service URL
SYNOPSIS
cc [ flag... ] file... -lslp [ library... ]
#include <slp.h>
SLPError SLPParseSrvURL(const char *pcSrvURL, SLPSrvURL** ppSrvURL);
DESCRIPTION
The SLPParseSrvURL() routine parses the URL passed in as the
argument into a service URL structure and returns it in the
ppSrvURL pointer. If a parser error occurs, returns
SLP_PARSE_ERROR. The structure returned in ppSrvURL should be
freed with SLPFree(). If the URL has no service part, the
s_pcSrvPart string is the empty string, "", that is, it is not
NULL. If pcSrvURL is not a service: URL, then the s_pcSrvType
field in the returned data structure is the URL's scheme,
which might not be the same as the service type under which the URL
was registered. If the transport is IP, the s_pcNetFamily field
is the empty string.
If no error occurs, the return value is the SLP_OK. Otherwise, if
an error occurs, one of the SLPError codes is returned.
PARAMETERS
pcSrvURL
A pointer to a character buffer containing the null
terminated URL string to parse. It is destructively
modified to produce the output structure. It may not be
NULL.
ppSrvURL
A pointer to a ponter for the SLPSrvURL structure to
receive the parsed URL. It may not be NULL.
ERRORS
This function or its callback may return any SLP error code. See the
ERRORS section in slp_api(3SLP).
EXAMPLES
Example 1: Using SLPParseSrvURL()
The following example uses the SLPParseSrvURL() function to parse the
service URL service:printer:lpr://serv/queue1:
SLPSrvURL* surl;
SLPError err;
err = SLPParseSrvURL("service:printer:lpr://serv/queue1", &surl);
ENVIRONMENT VARIABLES
SLP_CONF_FILE
When set, use this file for configuration.
