/* 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>>. */ #include <string.h> #include <stdlib.h> #ifndef _REENT_ONLY _PTR _DEFUN (vec_calloc, (n, size), size_t n _AND size_t size) { return _vec_calloc_r (_REENT, n, size); } #endif
