The best way to do this is with the select() call. This tells the KERNEL to let you know when a socket is available for use. You can have one process do i/o with multiple sockets with this call.

If you want to wait for a connect on sockets 4, 6 and 10 you might execute the FOLLOWING code snippet:

fd_set socklist;

FD_ZERO(&socklist); /* Always clear the structure first. */

FD_SET(4, &socklist);

FD_SET(6, &socklist);

FD_SET(10, &socklist);

if (select(11, NULL, &socklist, NULL, NULL) < 0)

perror("select");

The kernel will notify US as soon as a file DESCRIPTOR which is less than 11 (the first parameter to select()), and is a member of our socklist becomes available for writing. See the man page on select() for more details.
