msgv() is a version of the msg() function that takes a va_list for format arguments, allowing more complex reporting functions to built on top of the msg() functionality. Internally msg() calls msgv().

Returns:

the level argument.

Function Documentation

int msg	(	int	level,
		const char *	fmt,
			...
	)

msg() supports the nl_error() interface, but provides a considerable amount of additional functionality to support logging of messages within an application with multiple executables. Through command-line options, msg() can be configured to log to stderr and/or to a log file and/or to the memo application, and adds a timestamp to each message. See nl_error() for definition of the level options.

Returns:

the level argument.
