SLPFINDSRVTYPES(3SLP) Service Location Protocol Library Functions


NAME


SLPFindSrvTypes - find service types

SYNOPSIS


cc [ flag... ] file... -lslp [ library... ]
#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 in the 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).
