Detailed Description

Log implementation.

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,
			...
	)

Logs the errno string This function should be called by the suitable macro

Parameters

level	loglevel of the message
file	filename for debug logging
line	linenumber for debug logging
partition	mpd partition
fmt	format string to print
...	arguments for the format string

mympd_log_errno()

void mympd_log_errno	(	const char *	file,
		int	line,
		const char *	partition,
		int	errnum
	)

Logs the errno string This function should be called by the suitable macro

Parameters

file	filename for debug logging
line	linenumber for debug logging
partition	mpd partition
errnum	errno

set_loglevel()

void set_loglevel

(

int

level

)

Sets the loglevel

Parameters

level

loglevel to set

Variable Documentation

log_type

enum log_types log_type

Type of logging system

loglevel

_Atomic int loglevel

Loglevel

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"
}

Maps loglevels to terminal colors

loglevel_names

static

Initial value:

= {
    [LOG_EMERG] = "EMERG",
    [LOG_ALERT] = "ALERT",
    [LOG_CRIT] = "CRITICAL",
    [LOG_ERR] = "ERROR",
    [LOG_WARNING] = "WARN",
    [LOG_NOTICE] = "NOTICE",
    [LOG_INFO] = "INFO",
    [LOG_DEBUG] = "DEBUG"
}

Maps loglevels to names
