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 sup-
       port 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.
