I've been looking over the GNU Radio code and I can't seem to figure what is being done in /usrp2/host/lib/open_usrp2_socket.cc file. Specifically, lines 97 through to 128.
What I think is happening is that a pair of connected sockets is created (97) then a process is forked (102). So, the child process has it's own pair of sockets? Are sockfd[0] in each process connected? That would explain why sockfd[1] is closed (114) immediately after the fork, but it would not explain the need for socketpair to begin with. So, my questions are: why is socketpair needed? What is the fork doing? And, why is the socket closed right after the fork? Any help is appreciated. Devin
