Enumeration Type Documentation

enum decoder_state

Enumerator:

DECODE_STATE_STOP
DECODE_STATE_START
DECODE_STATE_DECODE
DECODE_STATE_ERROR	The last "START" command failed, because there was an I/O error or because no decoder was able to decode the file. This state will only come after START; once the state has turned to DECODE, by definition no such error can occur.
