With fcntl() you need to call fcntl() to get descriptor's current status flags, then call fcntl() again to set them. int int_val; int connfd; /* Set socket non-blocking */ int_val = 1; ioctl(connfd, FIONBIO, &int_val); /* Set socket blocking */ int_val = 0; ioctl(connfd, FIONBIO, &int_val); _______________________________________________ opensolaris-code mailing list opensolaris-code@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
