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 XineramaScreenInfo array.

DESCRIPTION

       Xinerama  is  a simple library designed to interface the Xinerama Extension 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 available,  the  return  value  is  True,  and
       event_base_return  and  error_base_return  are set to the base event number and base error
       number 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
       incompatible, it returns zero.

   XineramaIsActive()
       The  XineramaIsActive function returns a Boolean operator used to determine 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.   XineramaQueryScreens()  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  deprecated and this API should be used
       instead in new software.
