Q: How to get a local port number?

A: You do setsockopt() to set options and do socket(), bind().

Line 53 static int ox_connect(char *hostname, int port, ox_soc

struct sockaddr_in serv;

int s = getsocket(&serv, hostname, port);

if (connect(s, (struct sockaddr *)&serv, sizeof(serv)) != 0) {

fprintf(ox_stderr, "ox_connect: failed. socket = %d, errno = %d\n", s, errno);

ox_printf("ox_connect: failed. socket = %d, errno = %d\n", s, errno);

return -1;

}

return s;

Line 68 static int ox_listen(char *hostname, int *port, int ba

opt->option_value, opt->option_len);

if (bind(s_waiting, (struct sockaddr *)&me, sizeof(me)) < 0

|| listen(s_waiting, backlog) < 0) {

fprintf(ox_stderr, "ox_listen: failed.\n");

ox_printf("ox_listen: failed.\n");

return -1;

}

return s_waiting;

Line 79 static int ox_getport(int s_waiting)

struct sockaddr_in me;

int len = sizeof(me);

if (getsockname(s_waiting, (struct sockaddr *)&me, &len) < 0) {

fprintf(ox_stderr, "ox_getport: failed.\n");

ox_printf("ox_getport: failed.\n");

return -1;

}

return ntohs(me.sin_port);

Line 113 int mypipe(char *program, int fd1, int fd2)

int sockfd[2];

if (socketpair(AF_UNIX, SOCK_STREAM, 0, sockfd) < 0) {
