[ping] 2 small fixes

[olivier.coursiere@…]

• errx's error message should be ended with a new line
  • the type of fromlen in main function should match the type of the last

argument in recvfrom. So, fromlen should be "int" instead of "size_t".

[olivier.coursiere@…]

patch to fix those problems

[korli]

Thanks for the patch. On the second problem, I think it would be better anyway to use socklen_t in sys/socket.h instead of int. Axel, could changing to socklen_t make Haiku less BeOS compatible, etc.. ?

[axeld]

It would only affect source compatibility, and I wouldn't have a problem with that (but I don't expect any problems with this either) :-) IOW I'd welcome socklen_t.

[korli]

I'm wondering : we could only change it for our libnetwork.so and our headers, not the compat net libs and legacy network headers ?

[korli]

Committed the relevant part of the patch, and changed size parameter type of sys/socket.h functions to socklen_t for our own headers and libnetwork.so in revision 17911.
