/** Obtain a preview of the first input data of a fifo which was created
|

by burn_fifo_source_new(). The data will later be delivered normally to
|
||||
the consumer track of the fifo.
|
||||
bufsize may not be larger than the fifo size (chunk_size * chunks).
|
||||
This call will succeed only if data consumption by the track has not
|
||||
started yet, i.e. best before the call to burn_disc_write().
|
||||
It will start the worker thread of the fifo with the expectable side
|
||||
effects on the external data source. Then it waits either until enough
|
||||
data have arrived or until it becomes clear that this will not happen.
|
||||
The call may be repeated with increased bufsize. It will always yield
|
||||
the bytes beginning from the first one in the fifo.
|
||||
@param fifo The fifo object to inquire
|
||||
@param buf Pointer to memory of at least bufsize bytes where to
|
||||
deliver the peeked data
|
||||
@param bufsize Number of bytes to peek from the start of the fifo data
|
||||
@param flag Bitfield for control purposes (unused yet, submit 0).
|
||||
@return <0 on severe error, 0 if not enough data, 1 if bufsize bytes read
