NAME
       SLPFindSrvs - return service URLs

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

       SLPError SLPFindSrvs(SLPHandle hSLP, const char *pcServiceType,
	    const char *pcScopeList, const char *pcSearchFilter,
	    SLPSrvURLCallback *callback, void *pvCookie);

DESCRIPTION
       The  SLPFindSrvs()  function  issues a request for SLP services. The query is for services on a language-specific SLPHandle. It returns the
       results through the callback. The parameters will determine the results.

       If an error occurs  in starting the operation, one  of  the SLPError codes is returned.

PARAMETERS
       hSLP		 The language-specific SLPHandle on which to  search for services. It cannot  be NULL.

       pcServiceType	 The service type string for the request. The pcServiceType can be discovered by a call to SLPSrvTypes(). Examples of ser-
			 vice type strings include

			   "service:printer:lpr"

			 or

			   "service:nfs"

			 pcServiceType cannot be NULL.

       pcScopeList	 A pointer to a char containing a comma-separated  list  of scope names. It cannot be NULL or an empty string, "".

       pcSearchFilter	 A query formulated of attribute pattern matching expressions in the form of a LDAPv3 search filter. See RFC 2254. If this
			 filter is empty, "", all services of the requested type in the specified scopes are returned. It cannot be NULL.

       callback 	 A callback through which the results of the operation are reported. It cannot be NULL.

       pvCookie 	 Memory passed to the callback code from the client. It can be NULL.

ERRORS
       This function or its callback may return any SLP error code. See the ERRORS section in slp_api(3SLP).

	 SLPError err;
	 SLPHandle hSLP;
	 SLPSrvURLCallback srvngst;

	 err = SLPFindSrvs(hSLP,
			   "service:printer:lpr",
			   "default",
			   "(dpi=300)",
			   srvngst,
			   NULL);
