+.SH DESCRIPTION
+The
+.BR libsimple_aligned_memdup ()
+function constructs allocates memory with the alignment
+specified in the
+.I alignment
+parameter and copies
+.I n
+first bytes from
+.I s
+into the new allocation.
+.PP
+The
+.BR libsimple_enaligned_memdup ()
+and
+.BR libsimple_ealigned_memdup ()
+functions are versions of the
+.BR libsimple_aligned_memdup ()
+function that call the
+.BR libsimple_enprintf (3)
+function on failure, causing the process to print
+an error message and exit. See
+.BR libsimple_enprintf (3)
+for more information.
+.PP
+The
+.BR libsimple_memdupa ()
+function is implemented as a macro and is a version
+of the
+.BR libsimple_memdup ()
+function that uses allocates the memory on the stack
+rather than on the heap, causing the return pointer
+to become invalid when the calling function returns.
+.SH RETURN VALUE
+Upon successful completion, the
+.BR libsimple_aligned_memdupa (),
+.BR libsimple_aligned_memdup (),
+.BR libsimple_enaligned_memdup (),
+and
+.BR libsimple_ealigned_memdup ()
+functions return a non-null pointer, on failure the
+.BR libsimple_aligned_memdup ()
+function returns
+.B NULL
+and set
+.I errno
+to indicate the error, and the
+.BR libsimple_enaligned_memdup (),
+and
+.BR libsimple_ealigned_memdup ()
+functions exit the process group. The
+.BR libsimple_aligned_memdupa ()
+function cannot fail, however the kernel
+can kill the process with a
+.B SIGSEGV
+signal if the memory cannot be allocated.
+.PP
+The returned pointer should be deallocated when it
+is no longer needed, except for the pointer returned
+by the
+.BR libsimple_aligned_memdupa ()
+function, it is automatically deallocated when the
+calling function returns.
+.SH ERRORS
+The
+.BR libsimple_aligned_memdup ()
+function may fail for any reason specified for the
+.BR aligned_alloc (3)
+function.
