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.
COMPLIANCE
calloc
is ANSI.
Supporting OS subroutines required: close, fstat, isatty, lseek, read, sbrk, write.
