You have:
if(bind(s, (struct sockaddr *)&sa, sizeof(sa) < 0)) {
You want:
if(bind(s, (struct sockaddr *)&sa, sizeof(sa)) < 0) {

I have some code that is over 10 years old. With the recent change

4.0 my socket code won't compile anymore. The only way I can
compile my
code is if I use gcc_select. The problem is with the bind() call.
First, though I was getting strange compiler warnings.
comm.c: In function 'co1900_new_connection':
comm.c:1798: warning: pointer targets in passing argument 3 of
'getsockname'
differ in signedness
comm.c:1804: warning: pointer targets in passing argument 3 of

differ in signedness
comm.c: In function 'co2000_new_descriptor':
comm.c:1863: warning: pointer targets in passing argument 3 of
'getpeername'

1789: getsockname(s, (struct sockaddr *)&isa, &i);
1804: t = accept(s, (struct sockaddr *)&isa, &i);
1863: rc = getpeername(desc, (struct sockaddr *) &sock, &size);
I fixed the warnings by making (i) an unsigned int.
The bind code I am having a problem with is:
if(bind(s, (struct sockaddr *)&sa, sizeof(sa) < 0)) {
With gcc 3.3 no problems, but it is returning -1 with 4.0. I am no
socket
expert, and any debugging advice would help.
