Tests a memory address to make sure it represents a currently active memory block that was allocated by the diagnostic version of
const void* p,
LONG* plRequestNumber = NULL
Points to the block of memory to be tested.
Contains the length of the memory block in bytes.
Points to a
long integer that will be filled in with the memory block's allocation sequence number, or zero if it does not represent a currently active memory block.
Nonzero if the memory block is currently allocated and the length is correct; otherwise 0.
It also checks the specified size against the original allocated size. If the function returns nonzero, the allocation sequence number is returned in
plRequestNumber. This number represents the order in which the block was allocated relative to all other new allocations.
CAge* pcage = new CAge(21); // CAge is derived from CObject.
