I am playing around with the XI2 stuff and always get an error when using
XIQueryDevicePointer(). The function seems to do what its supposed to and
gives me the pointer coordinates, but as soon as I call it again or another
function like XCloseDisplay() I get an error like this:
XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0
after 13 requests (12 known processed) with 0 events remaining.
This is the code I used to query the virtual core pointer:
------------------------------------------------
int pointer = 2; // virtual core
int rx,ry,wx,wy;
unsigned int mask = 0;
Window root_return = 0, unused_window = 0;
Display *dpy = XOpenDisplay(NULL);
Window root = DefaultRootWindow(dpy);
[...query version for XI2...]
query_return =
XIQueryDevicePointer(dpy,pointer,root,&root_return,&unused_window,&rx,&ry,&wx,&wy,&mask);
[...print output...]
XCloseDisplay(dpy);
------------------------------------------------
Is this a bug or am I using the function incorrectly? (I am fairly new to X
programming).
Thanks in advance for any help.
