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.

"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.

SLPSrvURLCallback srvngst;

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