Detailed Description

Reimplemented from KProcess.

[virtual]

The buffer is zero terminated. A deep copy is made of the buffer, so you don't need to bother with that. A newline ( '\n' ) is appended unless you specify FALSE as the second parameter. FALSE is returned on an error, or else TRUE is.

Reimplemented from KProcess.

[virtual]

readln() reads up to '\n' (or max characters) and returns the number of characters placed in buffer. Zero is returned if no more data is available.

Use readln() in response to a readReady() signal. You may use it multiple times if more than one line of data is available. Be sure to use ackRead() when you have finished processing the readReady() signal. This informs KProcIO that you are ready for another readReady() signal.

readln() never blocks.

autoAck==TRUE makes these functions call ackRead() for you.

[virtual]

Reset the class. Doesn't kill the process.

[virtual]

Call this after you have finished processing a readReady() signal. This call need not be made in the slot that was signalled by readReady(). You won't receive any more readReady() signals until you acknowledge with ackRead(). This prevents your slot from being reentered while you are still processesing the current data. If this doesn't matter, then call ackRead() right away in your readReady()-processing slot.

Turns readReady() signals on and off. You can turn this off at will and not worry about losing any data. (as long as you turn it back on at some point...)
