#include  <sys/types.h>

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>.

Return values

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.
