XcupQueryVersion(3)						    X FUNCTIONS 					       XcupQueryVersion(3)

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.
