NAME

       XcupQueryVersion - Returns TOG-CUP protocol version supported by the X server

SYNOPSIS

       cc [ flag ... ] file ... -lXext [ library ... ]
       #include <X11/extensions/Xcup.h>

       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_version_return to the major and minor
       TOG-CUP protocol version 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  communications  with  the
       server,  or if the server and library protocol 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 XcupGetReservedColormapEntries.

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