int ev_gindev(devinfop, action)
struct devinfo *devinfop;
char action;
Description
ev_gindev
is used in concert with ev_getdev to exclude or later re-include
devices from feeding the event queue. The argument devinfop
contains the pointer to the device to be included or
excluded. The arguments are a pointer to the device and
EXCLUDE.
The pointer is obtained through the getdev function.
EXCLUDE is defined in <mouse.h>.
Diagnostics
This routine returns 0 if it succeeds. It returns -1 if there
is no active event queue. It returns -2 if the devinfo argument
does not point to a valid device. It returns -3 on attempts to
exclude an excluded device, or attempts to reinclude an included
device. It returns -4 if the action argument is invalid.
