-.SH DESCRIPTION
-The
-.BR libsimple_aligned_allocn (),
-.BR libsimple_enaligned_allocn (),
-and
-.BR libsimple_ealigned_allocn ()
-functions allocate
-.I N
-uninitialised 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 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_allocn ()
-and
-.BR libsimple_ealigned_allocn ()
-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_enaligned_allocn ()
-function is used or
-.IR libsimple_default_failure_exit (3)
-if the
-.BR libsimple_ealigned_allocn ()
-function is used.
-.PP
-The
-.BR libsimple_valigned_allocn (),
-.BR libsimple_envaligned_allocn (),
-and
-.BR libsimple_evaligned_allocn ()
-functions are versions of the
-.BR libsimple_aligned_allocn (),
-.BR libsimple_enaligned_allocn (),
-and
-.BR libsimple_ealigned_allocn (),
-respectively, that use
-.B va_list
-instead of variadic arguments.
-.SH RETURN VALUE
-The
-.BR libsimple_valigned_allocn (),
-.BR libsimple_envaligned_allocn (),
-.BR libsimple_evaligned_allocn (),
-.BR libsimple_aligned_allocn (),
-.BR libsimple_enaligned_allocn (),
-and
-.BR libsimple_ealigned_allocn ()
-functions return a pointer to the allocated memory
-upon success completion; otherwise the
-.BR libsimple_valigned_allocn ()
-and
-.BR libsimple_aligned_allocn ()
-functions return
-.B NULL
-and set
-.I errno
-it indicate the error, and the
-.BR libsimple_envaligned_allocn (),
-.BR libsimple_evaligned_allocn (),
-.BR libsimple_enaligned_allocn (),
-and
-.BR libsimple_ealigned_allocn ()
-functions terminated the process.
-.SH ERRORS
-The
-.BR libsimple_valigned_allocn (),
-.BR libsimple_aligned_allocn ()
-function will fail if:
-.TP
-.B EINVAL
-.I n
-is 0.
-.TP
-.B EINVAL
-.I n
-is not a multiple of
-.IR alignment .
-.TP
-.B EINVAL
-.I alignment
-is not a power of two.
-.TP
-.B ENOMEM
-Enough memory could not be allocated.
-.PP
-The
-.BR libsimple_envaligned_allocn (),
-.BR libsimple_evaligned_allocn (),
-.BR libsimple_enaligned_allocn (),
-and
-.BR libsimple_ealigned_allocn ()
-functions will terminate the process on failure.
