err(3) style logging API with console and syslog backends

lerr() - err(3) style logging API with console and syslog backends

This API supports logging by daemons, either to syslog or to the console. It is modelled after the API provided by the err(3) family of functions.

By default logging is output to the console via the err(3) API. However, if the daemon forks, the same API can be directed to syslog.

API

lerr(), lerrx(), lwarn(), and lwarnx() are equivalent to err(), errx(), warn(), and warnx() respectively.

linfo() and ldebug() can be used to log information at the LOG_INFO and LOG_DEBUG log levels in the syslog() backend. warnx() is used as the backend for these functions in console logger.

logger_syslog() is used to switch the logger from console output to syslog output. Internally it passes the progname argument as the ident argument to openlog(3).

Examples

if (!debug) {
	logger_syslog(getprogname());
}
linfo("program has started");

lerr's Issues

`lerrx` should be equivalent to `errx` in readme, not `lerr`
