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

minor_version_return

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.
