/* HP-UX has this oddity where it features a few functions that don't work
with socklen_t so we need to convert to ints
This is due to socklen_t being a 64bit int under 64bit ABI, but the
pre-xopen (default) interfaces require an int, which is 32bits.
Therefore, Anytime socklen_t is passed by pointer, the libc function
truncates the 64bit socklen_t value by treating it as a 32bit value.
Note that some socket calls are allowed to have a NULL pointer for
the socklen arg.
