* @param gc The connection over which to send the typing notification.
* @param name The user to send the typing notification to.
* @param state One of PURPLE_TYPING, PURPLE_TYPED, or PURPLE_NOT_TYPING.
* @return A quiet-period, specified in seconds, where Purple will not
* send any additional typing notification messages. Most
* protocols should return 0, which means that no additional
* PURPLE_TYPING messages need to be sent. If this is 5, for
* example, then Purple will wait five seconds, and if the Purple
* user is still typing then Purple will send another PURPLE_TYPING
