RxMapAndDissociateMidFromContext function (midatlax.h)
RxMapAndDissociateMidFromContext maps a Multiplex ID (MID) to its associated context in a MID_ATLAS structure and then disassociates the MID from the context.
Syntax
NTSTATUS RxMapAndDissociateMidFromContext(
PRX_MID_ATLAS MidAtlas,
USHORT Mid,
PVOID *ContextPointer
);
Parameters
MidAtlas
A pointer to the MID_ATLAS structure.
Mid
The multiplex ID to be mapped.
ContextPointer
A pointer that will hold the context for this MID on exit.
Return value
RxReassociateMid always returns STATUS_SUCCESS.
The returned pContextPointer parameter is a pointer to the associated context, or a NULL if no context was associated with this MID.
Remarks
RDBSS defines a Multiplex ID (MID), a 16-bit value, that can be used by both the network client (mini-redirector) and the server to distinguish between the concurrently active requests on any connection. A MID is a component of a MID_ATLAS data structure allocated by calling RxCreateMidAtlas. A MID_MAP data structure is allocated and used for mapping MIDs to RX_CONTEXT data structures.
