| Service Location Protocol Library Functions | SLPFindSrvTypes(3SLP) |
| | SLPFindSrvTypes - find service types |
SYNOPSIS
| |
#include <slp.h> SLPError SLPFindSrvTypes(SLPHandle hSLP, const char *pcNamingAuthority, const char *pcScopeList, SLPSrvTypeCallback *callback, void *pvCookie); |
| |
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.

-
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.

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
scope and default naming authority:
| |
SLPError err;
SLPHandle hSLP;
SLPSrvTypeCallback findsrvtypes;
err = SLPFindSrvTypes(hSLP, "", "default", findsrvtypes, NULL);
