NAME
       memalign() - allocate aligned memory

SYNOPSIS
DESCRIPTION
       allocates  space  for a block of size bytes, whose address is a multiple of boundary.  The space is not initialized. The boundary must be a
       power of 2.

EXTERNAL INFLUENCES
       employs the allocator.  For tuning information, see the malloc(3C) man page.

RETURN VALUE
       Upon successful completion, returns a pointer to space aligned to a multiple of boundary.  Otherwise, it returns a NULL pointer.

DIAGNOSTICS
       returns a NULL pointer if there is no available memory, or if the value of boundary is not a power of 2.

ERRORS
	      sets     to and returns a NULL pointer when an out-of-memory condition arises.

	      sets     to and returns a NULL pointer when the value of boundary is not a power of 2.

	      sets     to and returns a NULL pointer when the memory being managed by has been detectably corrupted.

WARNINGS
       For warnings, see the malloc(3C) man page.

SEE ALSO
       thread_safety(5).

STANDARDS CONFORMANCE
       There appear to be no standards applicable to Some implementations do not check that boundary is a power of 2.  The HP-UX implementation is
       not derived from any predecessor.
