+.SH PROLOG
+This manual page is part of the POSIX Programmer's Manual.
+The Linux implementation of this interface may differ (consult
+the corresponding Linux manual page for details of Linux behavior),
+or the interface may not be implemented on Linux.

+.SH NAME
+calloc
+\(em a memory allocator
+.SH SYNOPSIS
+.LP
+.nf
+#include <stdlib.h>
+.P
+void *calloc(size_t \fInelem\fP, size_t \fIelsize\fP);
+.fi
+.SH DESCRIPTION
+The functionality described on this reference page is aligned with the
+ISO\ C standard. Any conflict between the requirements described here and the
+ISO\ C standard is unintentional. This volume of POSIX.1\(hy2017 defers to the ISO\ C standard.
+.P
+The
+\fIcalloc\fR()
+function shall allocate unused space for an array of
+.IR nelem
+elements each of whose size in bytes is
+.IR elsize .
+The space shall be initialized to all bits 0.
+.P
+The order and contiguity of storage allocated by successive calls to
+\fIcalloc\fR()
+is unspecified. The pointer returned if the allocation succeeds shall
+be suitably aligned so that it may be assigned to a pointer to any type
+of object and then used to access such an object or an array of such
+objects in the space allocated (until the space is explicitly freed or
+reallocated). Each such allocation shall yield a pointer to an object
+disjoint from any other object. The pointer returned shall point to the
+start (lowest byte address) of the allocated space. If the space cannot
+be allocated, a null pointer shall be returned. If the size of the
+space requested is 0, the behavior is implementation-defined: either a
+null pointer shall be returned, or the behavior shall be as if the
+size were some non-zero value, except that the behavior is undefined
+if the returned pointer is used to access an object.
+.SH "RETURN VALUE"
+Upon successful completion with both
+.IR nelem
+and
+.IR elsize
+non-zero,
+\fIcalloc\fR()
+shall return a pointer to the allocated space. If either
+.IR nelem
+or
+.IR elsize
+is 0, then either:
+.IP " *" 4
+A null pointer shall be returned
+and
+.IR errno
+may be set to an implementation-defined value,
+or
+.IP " *" 4
+A pointer to the allocated space shall be returned. The application
+shall ensure that the pointer is not used to access an object.
+.P
+Otherwise, it shall return a null pointer
+and set
+.IR errno
+to indicate the error.
+.SH ERRORS
+The
+\fIcalloc\fR()
+function shall fail if:
+.TP
+.BR ENOMEM
+Insufficient memory is available.
+.LP
+.IR "The following sections are informative."
+.SH EXAMPLES
+None.
+.SH "APPLICATION USAGE"
+There is now no requirement for the implementation to support the
+inclusion of
+.IR <malloc.h> .
+.SH RATIONALE
+None.
+.SH "FUTURE DIRECTIONS"
+None.
