ANSI_SYNOPSIS
|

#include <stdlib.h>

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

TRAD_SYNOPSIS

#include <stdlib.h>

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

|

size_t <[n]>, <[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>>.
