  BOOL PASCAL AfxIsMemoryBlock( const void* p, UINT nBytes,
                                LONG* plRequestNumber = NULL );
 
  Parameter         Description
 
  <p>               A void pointer to the block of memory to be tested.
 
  <nBytes>          The length of the memory block in bytes.
 
  <plRequestNumber> A pointer to a long integer that will be filled in
                    with the memory block's allocation sequence number.
                    The variable pointed to by <plRequestNumber> will only
                    be filled in if AfxIsMemoryBlock returns TRUE.
 
  Remarks
 
  Tests a memory address to make sure it represents a currently active
  memory block that was allocated by the diagnostic version of new. It
  also checks the specified size against the original allocated size. The
  allocation sequence number that is returned in <plRequestNumber> if the
  function returns TRUE is the order in which the block was allocated
  relative to all other new allocations.
 
  Return Value
 
  TRUE if the memory block is currently allocated and the length is
  correct; otherwise FALSE.
 
  Example
 
  CAge* pcage = new CAge( 21 ); // CAge is derived from CObject
  if( AfxIsMemoryBlock( pcage, sizeof( CAge ) ) != TRUE )
      exit( 1 );   // Invalid memory
