vlc_Log()

void vlc_Log	(	struct vlc_logger *const *	logger,
		int	prio,
		const char *	type,
		const char *	module,
		const char *	file,
		unsigned	line,
		const char *	func,

vlc_LogDestroy()

void vlc_LogDestroy

(

struct vlc_logger *

logger

)

Destroys a message log.

vlc_LogHeaderCreate()

struct vlc_logger * vlc_LogHeaderCreate	(	struct vlc_logger *	parent,
		const char *	str
	)

Creates a prefixed message log.

This creates a message log that prefixes all its messages and forwards them in another log.

Parameters

parent	message log to inject into
str	nul-terminated prefix (a.k.a. "header")

Returns

a new message log on success or NULL on error
