NAME

1.10 `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 ALSO

calloc is part of the libc library. The full documentation for libc is maintained as a Texinfo manual. If info and libc are properly installed at your site, the command
info libc

will give you access to the complete manual.
