NAME
       Xinerama - API for Xinerama extension to X11 Protocol

SYNOPSIS
       #include <X11/extensions/Xinerama.h>

       Bool XineramaQueryExtension (Display *dpy,
	    int *event_base_return, int *error_base_return);

       Status XineramaQueryVersion (Display *dpy,
	    int *major_version_return,
	    int *minor_version_return);

       Bool XineramaIsActive (Display *dpy);

       XineramaScreenInfo * XineramaQueryScreens (Display *dpy,
	    int *number);

ARGUMENTS
       display	 Specifies the connection to the X server.

       event_base_return
		 Specifies  the	 return	 location  for the assigned base event
		 code

       error_base_return
		 Specifies the return location for  the	 assigned  base	 error
		 code

       major_version_return
		 Returns the major version supported by the server

       minor_version_return
		 Returns the minor version supported by the server

       number	 Returns the number of entries in the returned XineramaScreen‐
		 Info array.

DESCRIPTION
       Xinerama is a simple library designed to interface the Xinerama	Exten‐
       sion for retrieving information about physical output devices which may
       be combined into a single logical X screen.

FUNCTIONS
   XineramaQueryExtension()
       The XineramaQueryExtension function queries the	Xserver	 to  determine
       the  availability of the Xinerama Extension. If the extension is avail‐
       able,  the  return   value   is	 True,	 and   event_base_return   and
       error_base_return  are set to the base event number and base error num‐
       ber for the extension, respectively.  Otherwise, the  return  value  is
       False,  and  the	 values of event_base_return and error_base_return are
       undefined.

   XineramaQueryVersion()
       The XineramaQueryVersion function returns the version of	 the  Xinerama
       extension  implemented  by  the	Xserver.  The  version	is returned in
       major_version_return and minor_version_return. The major	 version  will
       be incremented for protocol incompatible changes, and the minor version
       will be incremented for small, upwardly compatible changes.

       If the Xinerama library is compatible with the version returned by  the
       server, it returns nonzero. If the server does not support the XINERAMA
       extension, or if there was an  error  during  communications  with  the
       server,	or  if the server and library protocol versions are incompati‐
       ble, it returns zero.

   XineramaIsActive()
       The XineramaIsActive function returns a Boolean operator used to deter‐
       mine  if	 Xinerama  is activated on the screen. Returns True for active
       and False for not active.

   XineramaQueryScreens()
       The XineramaQueryScreens() function returns info about each  individual
       output  device  within  the Xinerama Screen.  The integer pointed to by
       the number argument is updated to the number of output  devices	listed
       in  the	returned array of XineramaScreenInfo structures.  XineramaQue‐
       ryScreens() returns NULL and sets  number  to  0	 if  Xinerama  is  not
       active.

       The  pointer  returned  should be released with XFree(3) when no longer
       needed.

NOTE
       The original API provided for interacting with the  XINERAMA  extension
       used function names beginning with XPanoramiX.	That API is now depre‐
       cated and this API should be used instead in new software.
