IMalloc::DidAlloc

Determines if this allocator was used to allocate the specified block of memory.

int DidAlloc(

void *pv	//The pointer to the memory block
);

Parameter
pv
Specifies the pointer to the memory block; can be a NULL pointer, in which case, -1 is returned.

Return Values

The memory block was allocated by this IMalloc instance.

The memory block was not allocated by this IMalloc instance.

DidAlloc is unable to determine whether or not it allocated the memory block.

Comments
Calling IMalloc::DidAlloc is useful if a application is using multiple allocations, and needs to know whether a previously allocated block of memory was allocated by a particular allocation.
