XcupQueryVersion(3)        X FUNCTIONS        XcupQueryVersion(3)



NAME
       XcupQueryVersion  -  Returns TOG-CUP protocol version sup-
       ported by the X server

SYNOPSIS
       cc [ flag ... ] file ... -lXext [ library ... ]
       #include 

       Status XcupQueryVersion(Display *display,
              int *major_version_return, int *minor_version_return);

ARGUMENTS
       display   Specifies the connection to the X server

       major_version_return
                 Returns  the  major  version  supported  by  the
                 server

       minor_version_return
                 Returns  the  minor  version  supported  by  the
                 server

DESCRIPTION
       XcupQueryVersion sets major_version_return and  minor_ver-
       sion_return  to  the major and minor TOG-CUP protocol ver-
       sion supported by the server. If the  TOG-CUP  library  is
       compatible  with  the  version  returned by the server, it
       returns nonzero. If the server does not support  the  TOG-
       CUP  extension, or if there was an error during communica-
       tions with the server, or if the server and library proto-
       col  versions  are incompatible, it returns zero. No other
       Xcup functions may be called before this  function.  If  a
       client  violates  this rule, the effects of all subsequent
       Xcup calls that it makes are undefined.

       To get the list of reserved colormap entries, use  XcupGe-
       tReservedColormapEntries.

       To  allocate  one  or  more read-only color cells with RGB
       values, use XcupStoreColors.
