I'm sorry for posting twice but I think that my problem became easier to solve, because now I'm trying to convert both "linux_client.c" and "linux_server.c" (located in /rtnet-0.9.12/examples/generic/) and it's returning the same error: recvfrom(): Success
I simply changed socket() to rt_dev_socket(), bind() to rt_dev_bind(), sendto() to rt_dev_sendto(), recvfrom() to rt_dev_recvfrom() etc beyond adding "#include <rtdm/rtdm.h>" to the source files. What I'm doing wrong?
