Macros
#define	MICROSTRAIN_LOG_INIT(callback, level, user)   microstrain_logging_init(callback, level, user)

Functions
void	microstrain_logging_init (const microstrain_log_callback callback, const microstrain_log_level level, void *user)
	Initializes the logger with a callback and user data. Call MICROSTRAIN_LOG_INIT instead of using this function directly. This function does not have to be called unless the user wants logging. More...
microstrain_log_callback	microstrain_logging_callback (void)
	Gets the currently active logging callback. More...
microstrain_log_level	microstrain_logging_level (void)
	Gets the currently active logging level. More...
void *	microstrain_logging_user_data (void)
	Gets the currently active logging user data. More...
void	microstrain_logging_log_v (const microstrain_log_level level, const char *fmt, va_list args)
	Internal log function called by variadic logging macros. Call MICROSTRAIN_LOG_*_V macros instead of using this function directly. More...
void	microstrain_logging_log (const microstrain_log_level level, const char *fmt,...)
	Internal log function called by logging macros. Call MICROSTRAIN_LOG_* macros instead of using this function directly. More...
