RLog

RLog software provides flexible message logging for C programs and libraries. The software operates on a subscription-based model, where users can subscribe to messages of their choice in a number of ways. These include hierarchical channel name (e.g. "debug," "debug/special," "error," etc.), filename, component name, and more. Log messages are enabled individually and can be left in production code where they may be called many times.

RLog also offers add-on components that extend subscriptions to external programs, enabling debugging messages to be enabled and collected remotely. To begin using RLog in your code, you must define RLOG_COMPONENT in your build environment with a unique name for your program or library (not "rlog"). If your program is made up of separate components, you can define RLOG_COMPONENT as a different name for each component. It's recommended that you add a call to RLogInit() in your main program startup code, but it's not required.

To catch any messages you're interested in, add subscribers (rlog::StdioNode, rlog::SyslogNode, or your own). With this release, RLog underwent updates to compile with gcc 4.x or VC8, ensuring easier use in dynamic modules, and improving thread safety.

Overall, RLog is a highly recommended software that offers flexibility and ease of use for C programming and library messaging.
