cc [ flag... ] file... -lslp [ library... ] #include <slp.h> SLPError SLPFindAttrs(SLPHandle hSLP, const char *pcURL, const char *pcScopeList, const char *pcAttrIds, SLPAttrCallback *callback, void *pvCookie);
The SLPFindAttrs() function returns service attributes matching the attribute tags for the indicated full or partial URL.If pcURL is a complete URL, the attribute information returned is for that particular service in the language locale of the SLPHandle. If pcURL is a service type, then all attributes for the service type are returned, regardless of the language of registration. Results are returned through the callback parameter.
The result is filtered with an SLP attribute request filter string parameter, the syntax of which is described in RFC 2608. If the filter string is the empty string, "", all attributes are returned.
If an error occurs in starting the operation, one of the SLPError codes is returned.
pcURL
pcScopeList
pcAttrIds
callback
pvCookie
This function or its callback may return any SLP error code. See the ERRORS section in slp_api(3SLP).
Use the following example to return the attributes "location" and "dpi" for the URL "service:printer:lpr://serv/queue1" through the callback attrReturn:
SLPHandle hSLP; SLPAttrCallback attrReturn; SLPError err; err = SLPFindAttrs(hSLP "service:printer:lpr://serv/queue1", "default", "location,dpi", attrReturn, err);
Example 2 Returning Service Attributes for All URLs of a Specific Type
Use the following example to return the attributes "location" and "dpi" for all service URLs having type "service:printer:lpr":
err = SLPFindAttrs(hSLP, "service:printer:lpr", "default", "location, pi", attrReturn, NULL);
