No. I'd like to see a liberal license with this though. Curl is under a very liberal license. We'd like to see other programs use this macro for detecting socklen_t as well (lftp has adopted a derivative of it and KDE I think has). > > dnl Check for socklen_t: historically on BSD it is an int, and in > > dnl POSIX 1g it is a type of its own, but some platforms use different > > dnl types for the argument to getsockopt, getpeername, etc. So we > > dnl have to test to find something that will work. > > AC_DEFUN([TYPE_SOCKLEN_T], > > [ > > AC_CHECK_TYPE([socklen_t], ,[ > > AC_MSG_CHECKING([for socklen_t equivalent]) > > AC_CACHE_VAL([socklen_t_equiv], > > [ > > # Systems have either "struct sockaddr *" or > > # "void *" as the second argument to getpeername > > socklen_t_equiv= > > for arg2 in "struct sockaddr" void; do > > for t in int size_t unsigned long "unsigned long"; do > > AC_TRY_COMPILE([ > > #include <sys/types.h> > > #include <sys/socket.h> > > > > int getpeername (int, $arg2 *, $t *); > > A bit weird approach of checking for a compatible type, perhaps, but > if it works, then I'm all for it. Bruno, what do you think? BTW, having socklen_t doesn't mean it's used by some of the networking functions.
