I'm looking at the examples for mod_spidermonkey where streamFile can be interrupted by a DTMF.  There's dtmfcallback.js (http://wiki.freeswitch.org/wiki/Examples_dtmfcallback.js) and the Session_streamFile doc itself (http://wiki.freeswitch.org/wiki/Session_streamFile) They both use the third argument to the callback to get digits.digit or .duration, which I'm assuming is the length that the DTMF was pressed.  But, do the third or fourth arguments also include the position within the file?  I'm looking for a way to save the location in a voice prompt where a person pressed the DTMF -- either in seconds or samples or bytes from the beginning of the file. Also, for my own knowledge, is there a doc somewhere that explains all the possibile members of the third and fourth arguments (usually data and arg) in the callback from streamFile?  Thank you.
