Hello,
I´m using latest udpcast versión (20100130) in Debian machines to transfer files in unidirectional mode. Sometimes I see the next message in receiver machine: “Receiver error”
After putting some fprintf I realized the problem is in the file udpr-negotiate.c in line 191:
sock = udpc_selectSock(client_config.socks, NR_CLIENT_SOCKS,
net_config->startTimeout);if(sock < 0) {
return -1;}
Why sock is < 0? What should I do?
Sock is less than 0 if one of the 2 conditions if met: 1. "select" system call encounters an error. 2. select system call returns activity on no socket (i.e. timeout expired)
The select is used to tell which filedescriptor among several is ready for I/O (this allows udpcast to watch for several events at once, without knowing in advance which one would occur first).
1. Under normal circumstances, select should not fail, so I think we can rule this out. 2. If the startTimeout expires without any socket showing activity, sock is -1 as well. This would be the most common case where this happens.
Thanks
