编译运行
dong@ubuntu:~/nanomsg_demo$ gcc -o recv recv.c -lnanomsg
dong@ubuntu:~/nanomsg_demo$ ./recv
NODE0: RECEIVED 1 "hello,world !"
NODE0: RECEIVED 1 "hello,world !"
NODE0: RECEIVED 1 "hello,world !"
dong@ubuntu:~/nanomsg_demo$ gcc -o send send.c -lnanomsg
dong@ubuntu:~/nanomsg_demo$ ./send
NODE1: SENDING 1 "hello,world !"
dong@ubuntu:~/nanomsg_demo$ ./send
NODE1: SENDING 1 "hello,world !"
dong@ubuntu:~/nanomsg_demo$ ./send
NODE1: SENDING 1 "hello,world !"
