Return values:
Allocates storage areas and clears all bits in the allocated storage areas to 0.
<stdlib.h>
Normal:
nelem
elsize
Releases specified storage area.
<stdlib.h>
ptr
The calloc function allocates as many storage areas as specified by nelem, in as
Abnormal:
#include <stdlib.h>
size_t nelem, elsize;
void *ret;
many units of bytes as specified by elsize. The function also clears all the bits in
the allocated storage areas to 0.
#include <stdlib.h>
void *ptr;
The free function releases the storage area pointed by ptr, to enable reallocation
for use. If ptr is NULL, the function carries out nothing.
If the storage area attempted to release was not allocated by the calloc, malloc,
or realloc function, or if the area has already been released by the free or
realloc function, correct operation is not guaranteed. Operation result of
referencing an already released storage area is also undefined.
free(ptr);
ret=calloc(nelem, elsize);
Starting address of allocated storage area
If storage allocation failed, or if either of the parameter is 0:
NULL
Number of elements
Number of bytes occupied by a single element
Address of storage area to release
