FUNCTION

<<vec_calloc>>---allocate space for arrays

INDEX

        vec_calloc

INDEX

        _vec_calloc_r

ANSI_SYNOPSIS

        #include <stdlib.h>

        void *vec_calloc(size_t <[n]>, size_t <[s]>);

        void *vec_calloc_r(void *<[reent]>, size_t <n>, <size_t> <[s]>);

TRAD_SYNOPSIS

        #include <stdlib.h>

        char *vec_calloc(<[n]>, <[s]>)

        size_t <[n]>, <[s]>;

        char *_vec_calloc_r(<[reent]>, <[n]>, <[s]>)

        char *<[reent]>;

        size_t <[n]>;

        size_t <[s]>;

DESCRIPTION

Use <<vec_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 <<vec_calloc>> comes out of the same memory pool

used by <<vec_malloc>>, but the memory block is initialized to all zero

bytes.  (To avoid the overhead of initializing the space, use

<<vec_malloc>> instead.)

The alternate function <<_vec_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

<<vec_calloc>> is an non-ANSI extension described in the AltiVec Programming

Interface Manual.

Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,

<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
