Frees a huge memory block.
| #include <malloc.h> | Required only for function declarations |
void _hfree( void __huge *memblock );
| memblock | Pointer to allocated memory block |
The _hfree function deallocates a memory block; the freed memory is returned to the operating system. The memblock argument points to a memory block previously allocated through a call to _halloc. The number of bytes freed is the number of bytes specified when the block was allocated.
Note that attempting to free an invalid memblock argument (one not allocated with _halloc) may affect subsequent allocation and cause errors.
