calloc(), malloc(), realloc(), free() are the functions for used for dynamic allocation of memory. So, They are predefined functions we can use them by including stdlib.h.

malloc is called from user space. stdlib contains the extern declarations needed for malloc. The definition if malloc is present in stdlib (may be glib) which intern calls "brk".
This is system call which in calls sys_brk. This extends the heap memory by specified memory size.

I think it should be alloc.h. But it is not in the options. We can prefer standard library i.e (stdlib.h).
