DESCRIPTION These routines provide a general-purpose memory allocation package. They maintain a table of free blocks for efficient allocation and coalescing of free storage. When there is no suitable space already free, the allocation routines call sbrk() (see brk(2)) to get more memory from the system. Each of the allocation routines returns a pointer to space suitably aligned for storage of any type of object. Each returns a NULL pointer if the request cannot be completed. */ /* malloc - memory allocator. char *malloc(size) unsigned size; malloc() returns a pointer to a block of at least size bytes, which is appropriately aligned.
