Function Documentation

get_loglevel_name()

const char * get_loglevel_name

(

int

level

)

Returns the name of the loglevel

Parameters

level

Returns

the loglevel name or empty string if loglevel is invalid

log_init()

void log_init

(

void

)

Initializes the logging sub-system

mympd_log()

void mympd_log	(	int	level,
		const char *	file,
		int	line,
		const char *	partition,
		const char *	fmt,
			... )

Logging function This function should be called by the suitable macro

Loglevel.

Global variables

loglevel_colors

const char* loglevel_colors[8]

static

Initial value:

= {
    [LOG_EMERG] = "\033[0;31m",
    [LOG_ALERT] = "\033[0;31m",
    [LOG_CRIT] = "\033[0;31m",
    [LOG_ERR] = "\033[0;31m",
    [LOG_WARNING] = "\033[0;33m",
    [LOG_NOTICE] = "",
    [LOG_INFO] = "",
    [LOG_DEBUG] = "\033[0;32m"
