Hi all, I have been looking into non-blocking read (readline) operations on PIPES on windows XP and there seems to be no way of doing this. Ive read that you could use a Thread to read from the pipe, but if you still use readline() wouldnt the Thread block too?
What i need to do is, create a process using subprocess.Popen, where the subprocess outputs information on one line (but the info continuesly changes and its always on the same line) and read this information without blocking, so i can retrieve other data from the line i read in then put this in a GUI interface. readline() blocks until the newline character is read, but when i use read(X) where X is a number of bytes then it doesnt block(expected functionality) but i dont know how many bytes the line will be and its not constant so i cant use this too. Any ideas of solving this problem? Cheers -- http://mail.python.org/mailman/listinfo/python-list
