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

NAME
       SLPFindSrvs - return service URLs

SYNOPSIS
       #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 service 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).

EXAMPLES
       Example 1: Using SLPFindSrvs()

       The following example finds all advertisements for printers supporting the LPR protocol with the dpi attribute 300 in the default scope:

       SLPError err;
       SLPHandle hSLP;
       SLPSrvURLCallback srvngst;

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

ENVIRONMENT VARIABLES
       SLP_CONF_FILE	       When set, use this file for configuration.
