DESCRIPTION
32
Use <<calloc>> to request a block of memory sufficient to hold an
33
array of <[n]> elements, each of which has size <[s]>.
34
 
35
The memory allocated by <<calloc>> comes out of the same memory pool
36
used by <<malloc>>, but the memory block is initialized to all zero
37
bytes.  (To avoid the overhead of initializing the space, use
38
<<malloc>> instead.)
39
 
40
The alternate function <<_calloc_r>> is reentrant.
41
The extra argument <[reent]> is a pointer to a reentrancy structure.
42
 
43
RETURNS
44
If successful, a pointer to the newly allocated space.
45
 
46
If unsuccessful, <<NULL>>.
47
 
48
PORTABILITY
49
<<calloc>> is ANSI.
50
 
51
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
52
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
