You have to use the FD_* macros to create descriptor sets. If you want
to wait for a descriptor `fd' to become readable, you would use
something like:
int wait_for_read(int fd)
{
fd_set fds;
FD_ZERO(&fds);
FD_SET(fd, &fds);
if (select(fd + 1, &fds, NULL, NULL, NULL) < 0)
{
perror("select");
return 0;
}
return FD_ISSET(fd, &fds);
}
