To make the pcap_next/pcap_ex non blocking under Linux I use:
FD_ZERO(&m_fdset);
FD_SET(m_pcap_fd, &m_fdset);
m_fdtimeout.tv_sec = 0;
m_fdtimeout.tv_usec = CAP_READ_TIMEOUT*1000;
selRet = select(m_pcap_fd+1, &m_fdset, NULL, NULL, &m_fdtimeout);
No possibility to delete this ugly code with libpcap 1.0.0?
I've seen:
int pcap_setnonblock(pcap_t *p, int nonblock, char *errbuf);
Doesn't work under Linux?
