ldap_result (Windows CE 5.0)
This function obtains the result of an asynchronous operation.
ULONG ldap_result(LDAP* ld,ULONGmsgid,ULONGall,LDAP_TIMEVAL* timeout,LDAPMessage** res);
Parameters
- ld
[in] Session handle. - msgid
[in] Message identifier of the operation, or the constant LDAP_RES_ANY if any result is desired. - all
[in] Specifies how many messages will be retrieved in a single call to this function. This parameter only has meaning for search results. Pass the constant LDAP_MSG_ONE (0x00) to retrieve one message at a time. Pass LDAP_MSG_ALL (0x01) to request that all results of a search be received before returning all results in a single chain. Pass LDAP_MSG_RECEIVED (0x02) to indicate that all results retrieved so far should be returned in the result chain. - timeout
[out] A time-out specifying how long to wait (in seconds) for results to be returned. A NULL value causes this function to block until results are available. A time-out value of 0 seconds specifies a polling behavior. - res
[out] Contains the results of the operation.
Return Values
If this function succeeds, it returns one a value to indicate the type of the first result in the res parameter. The following table shows the possible return values.
| Return value |
|---|
| LDAP_RES_ADD |
| LDAP_RES_BIND |
| LDAP_RES_COMPARE |
| LDAP_RES_DELETE |
| LDAP_RES_EXTENDED |
| LDAP_RES_MODDN |
| LDAP_RES_MODIFY |
| LDAP_RES_SEARCH_ENTRY |
| LDAP_RES_SEARCH_REFERENCE |
| LDAP_RES_SEARCH_RESULT |
If the time-out expires, this function returns 0.
If this function fails, it returns –1 and sets the session error parameters in the LDAP data structure.
Remarks
This function retrieves the result of a previous, asynchronously initiated operation.
Note Depending on the way it is called, this function may actually return a list or "chain" of messages.
For connectionless LDAP, you must pass both an LDAP connection handle and a message identifier to ensure that you get the correct results. The LDAP run time continues to send the request until it receives a response.
In a multithreading environment, calls to this function are thread-safe.
Requirements
OS Versions: Windows CE .NET 4.0 and later.
Header: Winldap.h.
Link Library: Wldap32.lib.
