+FUNCTION
+<<calloc>>---allocate space for arrays
+
+INDEX
+	calloc
+
+INDEX
+	_calloc_r
+
+ANSI_SYNOPSIS
+	#include <stdlib.h>
+	void *calloc(size_t <[n]>, size_t <[s]>);
+	void *calloc_r(void *<[reent]>, size_t <n>, <size_t> <[s]>);
+	
+TRAD_SYNOPSIS
+	#include <stdlib.h>
+	char *calloc(<[n]>, <[s]>)
+	size_t <[n]>, <[s]>;
+
+	char *_calloc_r(<[reent]>, <[n]>, <[s]>)
+	char *<[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>>.
+
+PORTABILITY
+<<calloc>> is ANSI.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
