The MRxCollapseOpen routine is called by RDBSS to request that the network mini-redirector collapse an open file system request onto an existing SRV_OPEN structure.
RxContext [in, out] A pointer to the RX_CONTEXT structure. This parameter contains the IRP that is requesting the operation.
MRxCollapseOpen returns STATUS_SUCCESS on success or an appropriate NTSTATUS value, such as the following:
| Return code | Description |
|---|---|
| STATUS_INSUFFICIENT_RESOURCES | There were insufficient resources to complete the operation. |
MRxCollapseOpen is called by RDBSS to collapse an SRV_OPEN structure locally. The network mini-redirector is consulted to determine if a collapse is possible so there is no reason to call the network mini-redirector twice. If the network mini-redirector decides to collapse the SRV_OPEN structure, then it will do so and pass back a returnable status. A return value of STATUS_SUCCESS is a terminating return value. A different return value, for example, STATUS_MORE_PROCESSING_REQUIRED, is considered a non-terminating return value.
Before calling MRxCollapseOpen, RDBSS modifies the following members in the RX_CONTEXT structure pointed to by the RxContext parameter:
pRelevantSrvOpen is set to the SRV_OPEN structure to collapse.
Create.pSrvCall is set to the SRV_CALL structure associated with the SRV_OPEN.
If the network mini-redirector decides to collapse the SRV_OPEN structure, then the SrvOpen member of the RX_CONTEXT structure must be set to the collapsed SRV_OPEN structure.
