CALLOC(3)

NAME
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'.
