IMallocSpy::PreDidAlloc (Compact 2013)

3/26/2014

This method is called by COM just prior to invoking the IMalloc::DidAlloc method.

Syntax

void* PreDidAlloc(
  void* pRequest, 
  BOOL fSpyed 
);

Parameters

  • pRequest
    [in] Pointer the caller is passing to IMalloc::DidAlloc.
  • fSpyed
    [in] TRUE if the allocation was done while this spy was active, otherwise FALSE.

Return Value

The pointer for which allocation status is determined. This pointer is passed to the IMallocSpy::PostDidAlloc method as the fActual parameter.

Remarks

When a spy object implementing the IMallocSpy interface is registered with the CoRegisterMallocSpy function, COM calls this method immediately before any call to IMalloc::DidAlloc.

This method is included for completeness and consistency - it is not anticipated that developers will implement significant functionality in this method.

To determine whether the platform supports this interface, see Determining Supported COM APIs.
