+.SH DESCRIPTION
+The
+.BR libsimple_aligned_allocz (),
+.BR libsimple_enaligned_allocz (),
+and
+.BR libsimple_ealigned_allocz ()
+functions allocate
+.I n
+bytes to the heap and return a pointer with an
+alignment of
+.I alignment
+bytes to the allocated memory. 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 returned pointer as
+input when the allocated memory is no longer needed.
+.PP
+The
+.BR libsimple_enaligned_allocz ()
+and
+.BR libsimple_ealigned_allocz ()
+functions will terminate the process if the memory
+cannot be allocated of if the user tries to allocate
+0 bytes, 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_enaligned_allocz ()
+function is used or
+.IR libsimple_default_failure_exit (3)
+if the
+.BR libsimple_ealigned_allocz ()
+function is used.
+.PP
+The
+.BR libsimple_enaligned_allocz ()
+and

+functions behaviour is unspecified if

+is 0.
+.SH RETURN VALUE
+The
+.BR libsimple_aligned_allocz (),
+.BR libsimple_enaligned_allocz (),
+and
+.BR libsimple_ealigned_allocz ()
+functions return a pointer to the allocated memory
+upon success completion; otherwise the

+and set

+and

+.SH ERRORS

+.SH DESCRIPTION
+The
+.BR libsimple_memalignzn (),
+.BR libsimple_enmemalignzn (),
+and
+.BR libsimple_ememalignzn ()
+functions allocate
+.I N
+bytes to the heap and return a pointer with an
+alignment of
+.I alignment
+bytes 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 memory will be initialised
+with zeroes if
+.I clear
+is a non-zero value. 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_enmemalignzn ()
+and
+.BR libsimple_ememalignzn ()
+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_enmemalignzn ()
+function is used or
+.IR libsimple_default_failure_exit (3)
+if the
+.BR libsimple_ememalignzn ()
+function is used.
+.PP
+The
+.BR libsimple_vmemalignzn (),
+.BR libsimple_envmemalignzn (),
+and
+.BR libsimple_evmemalignzn ()
+functions are versions of the
+.BR libsimple_memalignzn (),
+.BR libsimple_enmemalignzn (),
+and
+.BR libsimple_ememalignzn (),
+respectively, that use
+.B va_list
+instead of variadic arguments.
+.SH RETURN VALUE
+The
+.BR libsimple_vmemalignzn (),
+.BR libsimple_envmemalignzn (),
+.BR libsimple_evmemalignzn (),
+.BR libsimple_memalignzn (),
+.BR libsimple_enmemalignzn (),
+and
+.BR libsimple_ememalignzn ()
+functions return a pointer to the allocated memory
+upon success completion; otherwise the
+.BR libsimple_vmemalignzn ()
+and
+.BR libsimple_memalignzn ()
+functions return
+.B NULL
+and set
+.I errno
+it indicate the error, and the
+.BR libsimple_envmemalignzn (),
+.BR libsimple_evmemalignzn (),
+.BR libsimple_enmemalignzn (),
+and
+.BR libsimple_ememalignzn ()
+functions terminated the process.
+.SH ERRORS
+The
+.BR libsimple_vmemalignzn (),
+.BR libsimple_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 ENOMEM
+Enough memory could not be allocated.
+.PP
+The
+.BR libsimple_envmemalignzn (),
+.BR libsimple_evmemalignzn (),
+.BR libsimple_enmemalignzn (),
+and
+.BR libsimple_ememalignzn ()
+functions will terminate the process on failure.
