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.SEE ALSO
