    logging error messages

    Hi,

    In programming, how to write error messages. I dont want to use printf's in all the threads as it is blocking function.

    What is the general way of logging messages. It will be of great help if you suggest me some good documentation.

    Thanks in advance

    Depends on the program, really, if it's an interactive one then outputting to stderr is appropriate, if it's a daemon then logging to a file is the way to go. If you're in a blocking thread, dump the message in shared memory and signal a message-handling thread to go handle it.
