2.11 `calloc'--allocate space for arrays
SYNOPSIS
#include <stdlib.h>
void *calloc(size_t N, size_t S);
void *_calloc_r(void *REENT, size_t N, size_t S);
DESCRIPTION
Use `calloc' to request a block of memory sufficient to hold an array
of N elements, each of which has size S.
The memory allocated by `calloc' comes out of the same memory pool
used by `malloc', but the memory block is initialized to all zero
bytes. (To avoid the overhead of initializing the space, use `malloc'
instead.)
The alternate function `_calloc_r' is reentrant. The extra argument
REENT is a pointer to a reentrancy structure.
RETURNS
If successful, a pointer to the newly allocated space.
If unsuccessful, `NULL'.
PORTABILITY
`calloc' is ANSI.
Supporting OS subroutines required: `close', `fstat', `isatty',
`lseek', `read', `sbrk', `write'.
SEE ALSOcalloc is part of the library. The full documentation for is main‐
