Detailed Description

Synchronization between child and parent communicating via a pipe-pair.

General remarks:
1. All non essential pointers can be set to NULL.
   e.g.
   - If <sync_counter> NULL then internal counter is used.
   - If <dest_file> NULL then nothing is printed.
   - If <warn> NULL then no warning is send.
   - If <intro_text> NULL then no intro text is printed.
2. An external sync-counter should only be used when there
   are several input/output communication pairs used.
