It should be socklen_t - the opengroup docs will give the exact definition.
There is no need for it to be size_t because it will never be 'large'.
size_t got used in far too many places (unfortunately) - places where
'int' would be fine. XNET (the opengroup body) managed to kill some
of them from the network specs before they caused too much trouble
with binary compatibility.
