RxMapMidToContext maps a Multiplex ID (MID) to its associated context in a MID_ATLAS structure.

Syntax

PVOID RxMapMidToContext(
  PRX_MID_ATLAS MidAtlas,
  USHORT        Mid
);

Parameters

MidAtlas

A pointer to the MID_ATLAS structure.

Mid

The multiplex ID to be mapped.

Return value

RxMapMidToContext returns a pointer to the associated context, or NULL if none exists.

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.
