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.

Requirements

Header objidl.h, objidl.idl
Library ole32.lib
Windows Embedded CE Windows CE 3.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
