socket() fails with EAFNOSUPPORT(247)   
I use QNX6.3.2 and facing some issues in socket operation.

socket() call fails with errno=247(EAFNOSUPPORT).

socket() is invoked with proper values,
AF_INET(2), SOCK_DGRAM(2), IPPROTO_UDP(17) and I verified
that all values are correct.

Somehow, the problem happens with only my load which has
multiple threads.
If I write down simple program invoking socket()
with the same arguments as the above,
socket() successes.

It seems there are not compatible libraries, etc.
linked when building my load. Honestly, I do not have clue.

I'm using -Vgcc_ntoppcbe -w0 with qcc/QCC
and using ntoppc-ld to build local libraries.

Is there anything that can affect simple socket operation?
I need to resolve the issue ASAP. So, I would appreciate
any inputs.

Make sure io-net is running and npm-tcpip.so is
loaded therein.

Re: RE: socket() fails with EAFNOSUPPORT(247)   
If I write a simple program to open socket, it works.
So, I think both are running in the board properly.
socket() fails only with my complete load.

A 'pidin me' or ls /dev/socket will
say for sure.

Make sure the program that doesn't work doesn't export
the SOCK envar to something non-existant.

Re: RE: RE: socket() fails with EAFNOSUPPORT(247)   
Our program doesn't use putenv() at all.

It seems that the problem is not related to what function we call
but to what we link with.

We tried with the same main program which calls only socket()
and display result:
- Link the main program with just system libraries -lc -lsocket -lrpc
     : socket() works fine
- Link the main program with our other modules, main program
     still does not call any other function except socket()
     : socket() fails

Note that the main program used above for 2 cases are exactly
the same. We just tried linking it with other libraries
and socket() fails when it's linked with our other modules.

The same result when -lrpc was excluded.

Maybe it's inheriting it.  Check out
'pidin env' on your program.

Re: RE: RE: RE: socket() fails with EAFNOSUPPORT(247)   
Compared pidin env between the working program and failing program
and they are exactly the same including SOCK.
