DESCRIPTION

26       XcupQueryVersion sets major_version_return and minor_version_return  to
27       the  major  and minor TOG-CUP protocol version supported by the server.
28       If the TOG-CUP library is compatible with the version returned  by  the
29       server,  it returns nonzero. If the server does not support the TOG-CUP
30       extension, or if there was an  error  during  communications  with  the
31       server,  or  if the server and library protocol versions are incompati‐
32       ble, it returns zero. No other Xcup functions may be called before this
33       function. If a client violates this rule, the effects of all subsequent
34       Xcup calls that it makes are undefined.
35
36       To get the list of reserved colormap entries,  use  XcupGetReservedCol‐
37       ormapEntries.
38
39       To  allocate  one  or  more  read-only color cells with RGB values, use
40       XcupStoreColors.
