curl/lib/setup_once.h
Daniel Stenberg 375cdf89ad With lots of help from Rich Rauenza(?) in bug #1733119, we introduce a fairly 
complicated work-around for 64bit HPUX compiles. We do the fix using inline
static functions to make them follow the header file properly and thus get
used fine in the test suite too etc.

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.
