function called by Reliable Transfer, when it requests retransmission in SDL diagram this signal is called (Req_RTX, RetransChunks)

Parameters:

all_data_acked - indicates whether or not all data chunks have been acked
new_data_acked - indicates whether or not new data has been acked
num_acked - number of bytes that have been newly acked, else 0
- number_of_addresses so many addresses may have outstanding bytes actually that value may also be retrieved from the association struct (?)
num_acked_per_address - array of integers, that hold number of bytes acked for each address
number_of_rtx_chunks - number indicatin, how many chunks are to be retransmitted in on datagram
chunks - array of pointers to data_chunk structures. These are to be retransmitted

Returns:

-1 on error, 0 on success, (1 if problems occurred ?)
