Tell SWF Studio about a FileSys event that you'd like to receive notifications for.
First available in version 3.5 build 314.
event - The name of the event you want notification enabled for. Valid values include: onCopyProgress.
result - Notification data for the specified event (see description of events for more detail).
When this method is called synchronously, a return object containing the output parameters is returned to the caller immediately.
name - onCopyProgress
type - triggered
result - "bytes_copied"
During an FileSys.copyFileAsync, the plugin sends the number of bytes copied. The frequency of these notifications is a factor of the specified buffer size, as set in chunkSize parameter.
function onCopyProgress(ret_obj, cb_obj, err_obj)
ssDebug.trace("value: " + ret_obj.result);
