What are the C logging API's out there?
Some of them I found are
- log4c
- pantheios
- lwl
Is anyone aware of other loggers.
Thanks.

I'd start with Sourceforge.net. As far as I know, most of the C++ Logging frameworks (such as log4cpp) haven't been updated in a while, but I don't know if that means they aren't useful/robust. (This is more for anyone else with the question, as this post was made almost a year ago...) |
I don't want to reinvent the wheel, so I am looking for a debug trace log system. Something tried, tested and efficient.

Hi. I need am application logging library, and am not satisfied with the one's I've tried out so far: log4cpp and log4cxx. Neither are type-safe. Also, when not logging there still seems to be a performance drag (although iw've not measured it). Other than that, though, the feature sets are pretty good. If anyone has experience with others and can make ... |

One log call is not necessarily going to be cheaper than two. One (not uncommon) way of implementing multiplication and division at the hardware level is via log and exponential tables. You might recall the the pentium FDIV bug (related to the hardware floating point division done by early pentium CPUs) was actually the result of an error in tables used ... |

29. Rotating Log cboard.cprogramming.com |
If they're having trouble passing arguments to functions, working with a variable number of arguments is going to be a bit much for them. What exactly is your log function going to do? Is there a constant format you're going to be outputting? Is it all just a bunch of random stuff? I feel you're overcomplicating things. You should just get ... |

What I have is a multithreaded server running pretty stable.

I have no solution, I just jumped in because there's zero replies after a while.... C# is still so new there aren't many familiar with it, and what little I've seen doesn't thrill me into getting involved.
