NdisClDeregisterSap function

NdisClDeregisterSap releases a previously registered SAP.

Syntax

NDIS_STATUS NdisClDeregisterSap(
  NDIS_HANDLE NdisSapHandle
);

Parameters

NdisSapHandle

Specifies the handle returned by NdisClRegisterSap.

Return Value

NdisClDeregisterSap can return one of the following:

Return code Description
NDIS_STATUS_PENDING
The call manager's ProtocolCmDeregisterSap function has been called to complete the requested operation. NDIS calls the client's ProtocolClDeregisterSapComplete function when this operation is completed.
NDIS_STATUS_FAILURE
The SAP already is being closed, so this is a redundant call. If NdisClRegisterSap returns anything other than NDIS_STATUS_PENDING, the client should make an internal call to its ProtocolClRegisterSapComplete function.

Remarks

NdisClDeregisterSap releases a SAP on which the client previously registered itself to receive incoming calls with NdisClRegisterSap.

The client should consider the given NdisSapHandle invalid as soon as it calls NdisClDeregisterSap.
