    creating files sequentially with a timer

    Hi all,

    i receive some data from the network and i want to store this data in a files on disk sequentially each 8 hours, example:

    At the beginning i create the file file_00001 and all received data will go to this file, after 6 hours i create a new file file_00002 and send the file_00001 over the network and so on...

    If you have an idea on how to this feel free to answer me.
    Thanks for your help.

    Well... we could tell you how to do it but you wouldn't learn much from that...

    Sit down and give it your best shot. If you run into trouble post your code and we'll see what we can do...

    Thanks for the reply, i have two problems :

    1. How to set a timer to 8 hours?
    2. How to stop writing in the precedent file (after timer expiration) and write data in a new one?

    Thanks.

    1) That will depend on the platform.... For long time delays I would use the system time() function and check it about once every 10 seconds with a timer... Once the required number of seconds are gone by, I would invoke my "switch files" subroutine.

    2) When the time limit expires close your current file, ship it out on the net, then open a new file. If you're keeping copies use either a timestamp or sequence number in the filename...

    1 Open file
    2 Start timer
    3 Write data
    4 Timer event -> close file -> send file
    5 goto 1
