coap_get_log_level()

coap_log_t coap_get_log_level

(

void

)

Returns the current log level.

Definition at line 60 of file debug.c.

Here is the caller graph for this function:

coap_log_impl()

void coap_log_impl	(	coap_log_t	level,
		const char *	format,
			...
	)

Writes the given text to COAP_ERR_FD (for level <= LOG_CRIT) or COAP_DEBUG_FD (for level >= LOG_WARNING).

The text is output only when level is below or equal to the log level that set by coap_set_log_level().
