Description

The SLPFindSrvs() function issues a request for SLP services. The query is for services on a language-specific SLPHandle. It returns the results through the callback. The parameters will determine the results.

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 services. It cannot be NULL.

pcServiceType

The service type string for the request. The pcServiceType can be discovered by a call to SLPSrvTypes(). Examples of service type strings include

"service:printer:lpr"

or

"service:nfs"

pcServiceType 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, "".

pcSearchFilter

A query formulated of attribute pattern matching expressions in the form of a LDAPv3 search filter. See RFC 2254. If this filter is empty, "", all services of the requested type in the specified scopes are returned. It cannot be NULL.

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.
