CImageAllocator::SetProperties

The SetProperties method specifies the number of buffers to allocate and the size of each buffer. This method overrides the CBaseAllocator::SetProperties method.

Syntax

  HRESULT SetProperties(
  ALLOCATOR_PROPERTIES *pRequest,
  ALLOCATOR_PROPERTIES *pActual
);

Parameters

pRequest

Pointer to an ALLOCATOR_PROPERTIES structure that contains the buffer requirements.

pActual

Pointer to an ALLOCATOR_PROPERTIES structure that receives the actual buffer properties.

Return Value

Returns an HRESULT value.

Remarks

This method calls CImageAllocator::CheckSizes to validate the requested buffer size. It also calls the base-class version of SetProperties.

Requirements

**  Header:** Declared in Winutil.h; include Streams.h.

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
