#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

DESCRIPTIONXcupQueryVersion 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.
