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.
