File Sink open/close question

[Hanz]

Hi!
Im using a message queue to count data, while the data is sinked to a file. Then if the counter reaches X i want the old file to be closed and continue sinking in a new file. Then again if reaches X to switch to the old file. So my bottom part code looks like that:

tb = top_block()
        tb.start()
        a=0
       
        while 1:
                if tb.sink_queue.count()>X:
                        tb.gr_file_sink_0.close()
                        tb.sink_queue.flush()
                        if a==0:
                                tb.gr_file_sink_0.open("PLACE_TO_SAVE\two")
                                a=1
                        else:
                                tb.gr_file_sink_0.open("PLACE_TO_SAVE\one")
                                a=0

Right now, it simply closes the first file, but does not begin with the second one. Can anyone help me with that? Thanks in advance

Hans:

Where are you "resetting X"?

I setted X some lines before as 1000. And the tb.sink_queue.count() is resetted by tb.sink_queue.flush() i thought.

Hanz,

This shouldn't make any difference, but the file_sink's 'open' function also closes any previously opened files. Try removing your call to 'close' and just rely on the open to close it, reopen the new file, and then when the work is called the next time, it will run 'do_update' to set up the handles properly.

Also, you can try throwing in some debug prints to make sure both paths are actually being called properly.

Tom
