How to implement a log?

I am finding a way to implement a log mechanism that several processes write their behaviors (mainly for error and execution sequence of processes) to it by C with Linux?

Just open a file that shared for multi-processes and let processes fprintf() to it? Any smart way to implement an option/mechanism that controls the level of log such as error/detail/high or something like it?

It would be better if you could refer me to a light opensource for this?

Thanks.

In other languages, log4c is very popular (log4j, log4net). It has a lot of functionality just baked in, and since it is so common, other developers who work on your code will be familiar with it.

Use syslog, it's the standard (POSIX) logging solution.

Using fprintf is ok, however I am not sure if fprintf is threadsafe, if not use a lock mechanism to block the fprintf call for multiple simultaneous accesses.
