void* calloc (  size_t  nmemb, size_t  size )

Allocate an array of nmemb objects whose sizeof is size. The array is cleared. The returned address is aligned on a phrase in memory.

void free (  void *  ptr  )

Free a previously allocated buffer with malloc or calloc. The given address must be a valid one.

void* malloc (  size_t  size  )

Memory allocation. It returns the address of a buffer which is phrase aligned in memory.

unsigned long rand (   )
