libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The slog*() functions send log messages to the system logger, slogger2. To send formatted messages, use vslogf(). If you have programs that scan log files for specified codes, you can use slogb() or slogi() to send a block of structures or int's, respectively.
This function is a varargs version of slogf().
