Subject: [Udpcast] exit code not passed if rx pipe fails
Message-ID: <4C59967E.4060101@ncbi.nlm.nih.gov>

Hello,

If udp-receiver is writing to a pipe and the pipe fails, udp-receiver 
will incorrectly exit with a returncode of zero. This is easily tested 
with a trivial pipe program that copies stdin to stdout, but exits with 
a nonzero status upon encountering eof.

Adding the following to startReceiver() in udpr-negotiate.c is 
sufficient to fix this behavior:

<---- cut here

int ret;
...
         if(pipePid) {
             ret=udpc_waitForProcess(pipePid, "Pipe");
         }
...
return ret;

<---- cut here
