+.SH DESCRIPTION
+The
+.BR libsimple_posix_memalignzn (),
+.BR libsimple_enposix_memalignzn (),
+and
+.BR libsimple_eposix_memalignzn ()
+functions allocate
+.I N
+bytes to the heap and store a pointer with an
+alignment of
+.I alignment
+bytes to the allocated memory in
+.IR memptr ,
+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 memory will be initialised
+with zeroes if
+.I clear
+is a non-zero value. The function
+.BR free (3)
+shall be called with the pointer stored in
+.I memptr
+as input when the allocated memory is no longer needed.
+.I *memptr
+remains unmodified on failure.
+.PP
+The
+.BR libsimple_enposix_memalignzn ()
+and
+.BR libsimple_eposix_memalignzn ()
+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_enposix_memalignzn ()
+function is used or
+.IR libsimple_default_failure_exit (3)
+if the
+.BR libsimple_eposix_memalignzn ()
+function is used.
+.PP
+The
+.BR libsimple_vposix_memalignzn (),
+.BR libsimple_envposix_memalignzn (),
+and
+.BR libsimple_evposix_memalignzn ()
+functions are versions of the
+.BR libsimple_posix_memalignzn (),
+.BR libsimple_enposix_memalignzn (),
+and
+.BR libsimple_eposix_memalignzn (),
+respectively, that use
+.B va_list
+instead of variadic arguments.
+.SH RETURN VALUE
+The
+.BR libsimple_vposix_memalignzn ()
+and
+.BR libsimple_posix_memalignzn ()
+functions return 0 upon successful completion;
+otherwise an error code is returned to indicate
+the error.
+.PP
+The
+.BR libsimple_envposix_memalignzn (),
+.BR libsimple_evposix_memalignzn (),
+.BR libsimple_enposix_memalignzn (),
+and
+.BR libsimple_eposix_memalignzn ()
+functions do not return a value, but
+terminated the process on failure.
+.SH ERRORS
+The
+.BR libsimple_vposix_memalignzn (),
+.BR libsimple_posix_memalignzn ()
+function will fail if:
+.TP
+.B EINVAL
+.I n
+is 0.
+.TP
+.B EINVAL
+.I alignment
+is not a power of two.
+.TP
+.B EINVAL
+.I alignment
+is not a multiple of
+.IR "sizeof(void *)" .
+.TP
+.B ENOMEM
+Enough memory could not be allocated.
+.PP
+The
+.BR libsimple_envposix_memalignzn (),
+.BR libsimple_evposix_memalignzn (),
+.BR libsimple_enposix_memalignzn (),
+and
+.BR libsimple_eposix_memalignzn ()
+functions will terminate the process on failure.
