malloc

C's standard library routine for storage allocation. It

takes the number of bytes required and returns a pointer to a

block of that size. Storage is allocated from a heap which

lies after the end of the program and data areas. Memory

allocated with malloc must be freed explicitly using the

"free" routine before it can be re-used.

gc is a storage allocator with garbage collection that is

intended to be used as a plug-in replacement for malloc.
