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).

Example 1: Using SLPFindSrvTypes()

The following example finds all service type names in the default
