WebIn short, the malloc does a memory allocator. malloc is defined as follows: void *malloc (size_t size); The malloc () function allocates unused space for an object whose size in bytes is specified by size and whose value is indeterminate. The return value from malloc is void *malloc (size_t size); WebThe flag is also cleared if a subsequent call to fork (2) by this process succeeds. Historical With UNIX V6, the argument list of an exec () call was ended by 0, while the argument list of main was ended by -1. Thus, this argument list was not directly usable in a further exec () call. Since UNIX V7, both are NULL.
