subject: blockreading from a pipe

Hello David!

Hmmz, is more or less correct.
I also found out that although my buffer is 8K (OS/2 doesn't give me more
bytes per read so a bigger buffer is of little use) my program sometimes
reads less bytes, even though It's reading in the middle of a file (I tried
piping the nodelist through it as a test).
Is this because of the asynchronousness (sp?) of the pipe?
Would it be possible to read 0 bytes although the program isn't at the end
of the file being piped, yet?
Can I increase this 8K limit somehow?
Blockread (pascal) is the fastest way of getting data (text) from stdin?

Greetz,
        Udo
