SLPFindSrvTypes(3SLP) Service Location Protocol Library Functions SLPFindSrvTypes(3SLP) NAME
SLPFindSrvTypes - find service types SYNOPSIS
#include <slp.h> SLPError SLPFindSrvTypes(SLPHandle hSLP, const char *pcNamingAuthority, const char *pcScopeList, SLPSrvTypeCallback *callback, void *pvCookie); DESCRIPTION
The SLPFindSrvTypes() function issues an SLP service type request for service types inthe scopes indicated by the pcScopeList. The results are returned through the callback parameter. The service types are independent of language locale, but only for services registered in one of the scopes and for the indicated naming authority. If the naming authority is "*", then results are returned for all naming authorities. If the naming authority is the empty string, "", then the default naming authority, IANA, is used. IANA is not a valid naming authority name. The SLP_PARAMETER_BAD error code will be returned if you include it explicitly. The service type names are returned with the naming authority included in the following format: service-type "." naming-authority unless the naming authority is the default, in which case, just the service type name is returned. If an error occurs in starting the operation, one of the SLPError codes is returned. PARAMETERS
hSLP The SLPHandle on which to search for types. It cannot be NULL. pcNamingAuthority The naming authority to search. Use "*" to search all naming authorties; use the empty string "" to search the default naming authority. It cannot be NULL. pcScopeList A pointer to a char containing a comma-separated list of scope names to search for service types. It cannot be NULL or an empty string, "". 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 SLPFindSrvTypes() The following example finds all service type names in the default scope and default naming authority: SLPError err; SLPHandle hSLP; SLPSrvTypeCallback findsrvtypes; err = SLPFindSrvTypes(hSLP, "", "default", findsrvtypes, NULL); ENVIRONMENT VARIABLES

SLPFindAttrs(3SLP) Service Location Protocol Library Functions SLPFindAttrs(3SLP) NAME
SLPFindAttrs - return service attributes SYNOPSIS
#include <slp.h> SLPError SLPFindAttrs(SLPHandle hSLP, const char *pcURL, const char *pcScopeList, const char *pcAttrIds, SLPAttrCallback *callback, void *pvCookie); DESCRIPTION
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. PARAMETERS
hSLP The language-specific SLPHandle on which to search for attributes. It cannot be NULL. pcURL The full or partial URL. See RFC 2608 for partial URL syntax. It 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, "". pcAttrIds The filter string indicating which attribute values to return. Use empty string "" to indicate all values. Wild- cards matching all attribute ids having a particular prefix or suffix are also possible. It cannot be NULL. callback A callback function through which the results of the operation are reported. It cannot be NULL. pvCookie Memory passed to the callback code from the client. It may 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: Returning Service Attributes for a Specific URL Use the following example to return the attributes "location" and "dpi" for the URL "service:printer:lpr://serv/queue1" through the call- back 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); ENVIRONMENT VARIABLES
