Return values:
Return values:
Allocates a storage area.

Normal:
<stdlib.h>
Normal:
size
size
Changes the size of a storage area to a specified value.
ptr
#include <stdlib.h>
size_t size;
void *ret;
The malloc function allocates a storage area of a specified number of bytes by
size.
#include <stdlib.h>
size_t size;
void *ptr, *ret;
The realloc function changes the size of the storage area specified by ptr to the
number of bytes specified by size. If the newly allocated storage area is smaller
than the old one, the contents are left unchanged up to the size of the newly
allocated area.
If the storage area pointed by ptr 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.
Abnormal:
Abnormal:
ret=malloc(size);
ret=realloc(ptr, size);
Starting address of allocated storage area
If storage allocation failed, or if size is 0: NULL
If storage area allocation failed, or if size is 0: NULL
Size in number of bytes of storage area to allocate
Starting address of storage area whose size has been changed
Starting address of storage area to be changed
Size of storage area in number of bytes after the change
