Hi group,

I have this suite of program that use threads and fork/exec calls.
The programs now run OK with a major problem, the problem is that
sftp does not flush the output file buffer in a timely matter.
Here is a general description of how things work:

1. client starts thread to connect to server
2. client starts sftp using pseudo ttys.
3. client start thread to process sftp output
4. client start thread to process console input
5. client start thread to process server messages
6. client waits for files names from server
7. when filename comes in send, transfer request to sftp
8. when sftp outputs it is done, call file processor with filename
9. return to wait.

The problem is that the first filename is processed just fine. All the next filename get errors while being processed. If I add a sleep(1) delay before calling the file processor, everything works, but there is an added wait! This is a real time program and I can't afford the extra delay.

I tried adding a 'sync()', that did not help.

My question is, how can I force sftp to flush his buffer sooner??

Thanks for your time.
