Re: posix_memalign not available

Mihael:

No "memalign" function is needed on OS/400 or i5/OS. All allocations 
from the are always aligned on a quadword (16 byte) boundary, unless you 
take actions to override this default behavior.

Consider what happens if you allocate a chunk of memory to contain a 
data structure that contains one or more MI pointers.  If the allocated 
block was not aligned on a quadword, how would you ever know that the MI 
pointers within your data structures would be properly aligned (at runtime)?
