[Tirant]

I was able to successfully implement my idea. The code started getting a bit ugly because I didn't write any new functions to assist with the copying, but it works. Next step is to clean up what I've done and add two remaining features:

1) get calling function name (so in the logs one could have plugin::function, like in C)
2) add option to print stack trace following the message (this will be default for WARN and ERROR severities) The idea is to have format similar to Java (so this format may be fixed, however that is not out of the question to change):

exception in thread "main" java.lang.NullPointerException
        at com.example.myproject.Book.getTitle(Book.java:16)
        at com.example.myproject.Author.getBookTitles(Author.java:25)
        at com.example.myproject.Bootstrap.main(Bootstrap.java:14)

E.g.:

[ERROR] [21:54:38] [plugin1.sma::function1] Reason: Invalid handle specified (4)
        at function1(plugin1.sma:11)
        at function2(plugin2.sma:11)
        at function3(plugin2.sma:12)

I've uploaded a file generated using:

new Logger:logger = LoggerCreate(
        .verbosity = DEFAULT_LOGGER_VERBOSITY,
        .nameFormat = "loggerTest_%d",
        .msgFormat = "[%s] [%t] %n::%f %l",
        .dateFormat = "%Y-%m-%d",
        .timeFormat = "%H:%M:%S",
        .path = "");
LoggerSetVerbosity(logger, Severity_Debug);
LoggerLog(logger, Severity_Debug, "This is test %d", 1);
LoggerLog(logger, Severity_Info, "This is %s %f", "test", 2.0);
LoggerLog(logger, Severity_Warn, "This is test 3");
LoggerLog(logger, Severity_Error, "This is test 4");

LoggerLog(logger, Severity_Error, "This is a test with %s", "Exta stuffz");
LoggerDestroy(logger);

You can see already that this module offers a lot more flexibility in formatting logs the way you want, to see the messages you want to see.
