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.
