Functions
enum u_logging_level	u_log_get_global_level (void)
	Returns the global logging level, subsystems own logging level take precedence. More...
void	u_log_set_sink (u_log_sink_func_t func, void *data)
	Sets the logging sink, log is still passed on to the platform defined output as well as the sink. More...
static void	u_log_hexdump_line (char *buf, size_t offset, const uint8_t *data, size_t data_size)
void	u_log_hex (const char *file, int line, const char *func, enum u_logging_level level, const uint8_t *data, const size_t data_size)
	Log implementation for dumping memory buffers as hex: do not call directly, use a macro that wraps it. More...
void	u_log_xdev_hex (const char *file, int line, const char *func, enum u_logging_level level, struct xrt_device *xdev, const uint8_t *data, const size_t data_size)
	Device-related log implementation for dumping memory buffers as hex: do not call directly, use a macro that wraps it. More...
