+.SH DESCRIPTION
+The
+.BR libsimple_enposix_memalign ()
+and
+.BR libsimple_eposix_memalign ()
+functions allocate
+.I n
+uninitialised bytes to the heap and store a
+pointer with an alignment of
+.I alignment
+bytes to the allocated memory in
+.IR memptr .
+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_memalign ()
+and
+.BR libsimple_eposix_memalign ()
+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_enposix_memalign ()
+function is used or
+.IR libsimple_default_failure_exit (3)
+if the
+.BR libsimple_eposix_memalign ()
+function is used. Failure include,
+.I alignment
+not being a power of two, or
+.I alignment
+not being a multiple of
+.IR "sizeof(void *)" .
+.PP
+The
+.BR libsimple_enposix_memalign ()
+and
+.BR libsimple_eposix_memalign ()
+functions behaviour is unspecified if
+.I n
+is 0.
+.SH RETURN VALUE
+The
+.BR libsimple_enposix_memalign ()
+and
+.BR libsimple_eposix_memalign ()
+functions do not return a value, but
+terminated the process on failure.
+.SH ERRORS
+The
+.BR libsimple_enposix_memalign ()
+and
+.BR libsimple_eposix_memalign ()
+functions will terminate the process on failure.
