Ladies and Gents, John Galbraith has been writing a new GPIB driver. His effort appears to be targeted at a 2.2.x system. I'm trying to make his stuff work under -current, and I have run into a problem with the use of poll versus select in -current. In particular, the changes in revision 1.34 of sys/sys/conf.h have eliminated d_select_t and noselect which John uses. The d_select_t can be replaced by d_poll_t, but does one do about the noselect. This snippet is the part of the code in question. /* device switch entry table */ struct cdevsw gp_cdevsw = { (d_open_t *) gp_open, /* open */ (d_close_t *) gp_close, /* close */ (d_read_t *) gp_read, /* read */ (d_write_t *) gp_write, /* write */ (d_ioctl_t *) gp_ioctl, /* ioctl */ (d_stop_t *) nullstop, /* stop */ (d_reset_t *) nullreset, /* reset (not used) */ (d_devtotty_t *) nodevtotty,/* ttys */ (d_select_t *) noselect, /* select */ (d_mmap_t *) nommap, /* mmap */ (d_strategy_t *) nostrategy,/* strategy */ (char*) "gp", /* name */ NULL, /* struct bdevsw* */ -1 /* GP_CDEV_MAJOR */ /* major number of driver */ }; Is this the proper way to support both -current and 2.2.x? #ifdef __FreeBSD__ >= 3 (d_poll_t *) nopoll, #else (d_select_t *) noselect; #endif -- Steve finger kargl@troutmask.apl.washington.edu http://troutmask.apl.washington.edu/~clesceri/kargl.html To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
