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 incompati-
       ble, 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  XcupGetReservedCol-
       ormapEntries.

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