Constructs a CBaseAllocatorobject.

Syntax 

CBaseAllocator(
  TCHAR* 
pName,
  LPUNKNOWN 
lpUnk,
  HRESULT* 
phr,
  BOOL 
bListSemaphore = TRUE
);

Parameters

pName

Name of the allocator object.

lpUnk

Pointer to LPUNKNOWN.

phr

Pointer to an HRESULTfor return values. This is not modified unless this member function fails.

bListSemaphore

If TRUE, the free list in the allocator has a semaphore associated with it.

If FALSE, no semaphore is created for the list.

Setting this to FALSE can be useful for subclassing CBaseAllocatorwhen the semaphore is not required for blocking. The semaphore is used for the waiting and signaling mechanism.

Return Value

None.
