Re: [Dev-C++] integer to string

[Per W. <pw...@ia...>]

free() ignores the contents of your array. All you need is the pointer you
originally received from malloc() or calloc(). free() will then release
the full block - unless you for some reason has managed to break the heap
by writing outside of the allocated area (or actually to write immediately
BEFORE the returned pointer) and thereby destroy the heap management that
is almost always part of the allocated memory block.
