The Cancel method cancels any outstanding blocking
operation in the client, causing the blocking method to fail. The
application may then retry the operation or terminate the client
session.
Parameters
None.
Return Value
If the method succeeds, the return value is zero. If the method
fails, the return value is FTP_ERROR. To get extended error
information, call GetLastError.
Remarks
When the Cancel method is called, the blocking method will
not immediately fail. An internal flag is set which causes the
blocking operation to exit with an error. This means that the
application cannot cancel an operation and immediately perform some
other operation. Instead it must allow the calling stack to unwind,
returning back to the blocking operation before making any further
function calls.
