 Name

    ev_gindev - include/exclude devices for event input

 Syntax


    cc  . . .  -levent


    #include  <sys/types.h>
    #include  <sys/param.h>
    #include  <sys/sysmacros.h>
    #include  <sys/page.h>
    #include  <sys/event.h>
    #include  <mouse.h>

    int ev_gindev(devinfop, action)
    struct devinfo *devinfop;
    char action;


 Description

    evgindev is used in concert with evgetdev to exclude or later re-
    include devices from feeding the event queue. The argument devinfop con-
    tains 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 de-
    vice, or attempts to reinclude an included device. It returns -4 if the
    action argument is invalid.
