void proc_thread(BIGPROC *bigprocptrin, unsigned int offsetin)

where BIGPROC structure contains control parameters including pointers to the input (BIGBUF *gbigBuffer) and output (BIGBUF *gbigBuffer1) big buffers.

write_thread

Last component in coda_roc running as a thread. Main file is 'dac.s/roc_network.c'. Main function started as a thread is

write_thread(BIGNET *bignetptrin, unsigned int offsetin)

where BIGNET structure contains control parameters including pointers to the input (BIGBUF *gbigBuffer) big buffer;

rc directory (run control)

Uses MOTIF as graphics and ACE3.1 as communication package, all sources are available in subdirectories /cg, /motif and /sase3.1. Run control code resides in subdirectory /runControl.
