Subject: Where's the source Luke?
Can someone tell me where to find the source code for ioctl()? I've
searched all the .c files under /usr/src/sys and have found plenty
of functions called xxxx_ioctl, e.g. kbd_ioctl(), but not a plain
``ioctl()''.
I'm beginning to think that a call to ioctl() gets mapped to some
function specific to the device.
The particular instance I'm interested in is in video_mode() in
vidcontrol.c:
if (*index < argc) {
for (i = 0; modes[i].name != NULL; ++i) {
if (!strcmp(argv[*index], modes[i].name)) {
mode = modes[i].mode;
break;
}
}
if (modes[i].name == NULL)
return;
=====>> if (ioctl(0, mode, NULL) < 0) <<===============
warn("cannot set videomode");
Thanks.
