XineramaGetCenterHint(3X11) X11R6 XineramaGetCenterHint(3X11)
NAME
XineramaGetCenterHint - returns a hint for window placement
SYNTAX
#include <X11/extensions/Xinerama.h>
Status XineramaGetCenterHint(
Display *dpy,
int screen_number,
int *x_return,
int *y_return
);
ARGUMENTS
dpy Specifies the connection to the X server.
screen_number
Specifies a given Xinerama screen.
x_return,y_return
Returns a position about which a window may be centered
without overlapping more than one physical screen.
DESCRIPTION
XineramaGetCenterHint returns a hint about where to center
the window in order to have a nice layout. This allows us to
avoid having windows centered on the screen that are split
across two or more physical screens (frame buffers).
XineramaGetCenterHint returns True if the given screen is an
active Xinerama screen, False otherwise. An active Xinerama
screen is a large logical screen composed of multiple
underlying physical screens (also called frame buffers).
DIAGNOSTICS
BadValue
screen_number is out of range.
NOTES
Currently, all the physical screens managed by the Xinerama
enabled X server are combined into one active Xinerama
screen. This means that screen_number should be 0.
Xinerama is still not an Xorg standard. Thus, the interface
may still evolve.
