Hi,
You have told us what this patch does, but not why anyone should care.
Just a sentence or two is probably enough. Are you getting compiler
warnings (if so, what are they). Are we violating some standard (which
one).
Is there a connection between defining _POSIX_C_SOURCE (as described in
the subject) and the second argument to connect (as mentioned in the
comment above) and the second argument to bind (as not mentioned until
the code).
Please explain.
Thanks,
NeilBrown
