Detailed Description

Function Documentation

bool libcwd::test_delete ( void const *  void_ptr)

Test if a pointer points to the start of an allocated memory block.

Returns
true when ptr does not point to the start of an allocated memory block.  No checks are performed on the type of allocator that was used: that is done when the memory block is actually deleted, see De-Allocation Pointer Validation.

Unlike find_alloc, test_delete also works for invisible memory blocks.
