Returns the size of a memory block allocated in the heap.
size_t _msize( void *memblock );
- Pointer to memory block.
_msize returns the size (in bytes) as an unsigned integer.
The _msize function returns the size, in bytes, of the memory block allocated by a call to calloc, malloc, or realloc.
When the application is linked with a debug version of the C run-time libraries, _msize resolves to _msize_dbg. For more information about how the heap is managed during the debugging process, see The CRT Debug Heap.
