SLPFINDSRVTYPES(3SLP)SLPFINDSRVTYPES(3SLP)NAMESLPFindSrvTypes - 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 nam‐
ing 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 opera‐
tion 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:

SLPHandle hSLP;
SLPSrvTypeCallback findsrvtypes;
err = SLPFindSrvTypes(hSLP, "", "default", findsrvtypes, NULL);
