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.
