+.SH DESCRIPTION
+The
+.BR libsimple_vallocn (),
+.BR libsimple_envallocn (),
+and
+.BR libsimple_evallocn ()
+functions allocate
+.I N
+uninitialised bytes to the heap and return a
+pointer with an alignment of the page size
+to the allocated memory, where
+.I N
+is the product of
+.I n
+and all following arguments (which should have the type
+.BR size_t )
+up to the first 0;
+.I n
+must not be 0. The function
+.BR free (3)
+shall be called with the returned pointer as
+input when the allocated memory is no longer needed.
+.PP
+The
+.BR libsimple_envallocn ()
+and
+.BR libsimple_evallocn ()
+functions will terminate the process if the memory
+cannot be allocated, by calling the
+.BR libsimple_enprintf ()
+and
+.BR libsimple_eprintf ()
+functions, respectively.
+On failure, the process's exit value will be
+.I status
+if the
+.BR libsimple_envallocn ()
+function is used or
+.IR libsimple_default_failure_exit (3)
+if the
+.BR libsimple_evallocn ()
+function is used.
+.PP
+The
+.BR libsimple_vvallocn (),
+.BR libsimple_envvallocn (),
+and
+.BR libsimple_evvallocn ()
+functions are versions of the
+.BR libsimple_vallocn (),
+.BR libsimple_envallocn (),
+and
+.BR libsimple_evallocn (),
+respectively, that use
+.B va_list
+instead of variadic arguments.
+.SH RETURN VALUE
+The
+.BR libsimple_vvallocn (),
+.BR libsimple_envvallocn (),
+.BR libsimple_evvallocn (),
+.BR libsimple_vallocn (),
+.BR libsimple_envallocn (),
+and
+.BR libsimple_evallocn ()
+functions return a pointer to the allocated memory
+upon success completion; otherwise the
+.BR libsimple_vvallocn ()
+and
+.BR libsimple_vallocn ()
+functions return
+.B NULL
+and set
+.I errno
+it indicate the error, and the
+.BR libsimple_envvallocn (),
+.BR libsimple_evvallocn (),
+.BR libsimple_envallocn (),
+and
+.BR libsimple_evallocn ()
+functions terminated the process.
+.SH ERRORS
+The
+.BR libsimple_vvallocn (),
+.BR libsimple_vallocn ()
+function will fail if:
+.TP
+.B EINVAL
+.I n
+is 0.
+.B ENOMEM
+Enough memory could not be allocated.
+.PP
+The
+.BR libsimple_envvallocn (),
+.BR libsimple_evvallocn (),
+.BR libsimple_envallocn (),
+and
+.BR libsimple_evallocn ()
+functions will terminate the process on failure.
