D3DMEMORYPRESSURE structure (D3d9types.h) for Microsoft Media Foundation

  • Article

Contains data for memory pressure reporting.

Syntax

typedef struct _D3DMEMORYPRESSURE {
  UINT64 BytesEvictedFromProcess;
  UINT64 SizeOfInefficientAllocation;
  DWORD  LevelOfEfficiency;
} D3DMEMORYPRESSURE;

Members

BytesEvictedFromProcess

The number of bytes that were evicted by the process during the duration of the query.

SizeOfInefficientAllocation

The total number of bytes placed in nonoptimal memory segments, due to inadequate space within the preferred memory segments.

LevelOfEfficiency

The overall efficiency of the memory allocations that were placed in nonoptimal memory. The value is expressed as a percentage. For example, the value 95 indicates that the allocations placed in nonpreferred memory segments are 95% efficient. This number should not be considered an exact measurement.
