Function Documentation

void hexdump	(	char *	prefix,
		unsigned char *	buf,
		int	len
	)

Print prefix + a hex dump of len bytes starting at *buf.

Definition at line 339 of file lirc_log.c.

int lirc_log_close

(

void

)

Close the log previosly opened with lirc_log_open().

Definition at line 119 of file lirc_log.c.

loglevel_t lirc_log_defaultlevel

(

void

)

Get the default level, from environment or hardcoded.

Definition at line 201 of file lirc_log.c.

int lirc_log_get_clientlog	(	const char *	basename,
		char *	buffer,
		ssize_t	size
	)

Retrieve a client path for logging according to freedesktop specs.

Parameters

basename	Basename for the logfile.
buff	Buffer to store result in.
size	Size of buffer

Returns

0 if OK, otherwise -1

Definition at line 310 of file lirc_log.c.

int lirc_log_open	(	const char *	progname,
		int	_nodaemon,
		loglevel_t	level
	)

Open the log for upcoming logging

Parameters

progname	Name of application, made available in global progname
nodaemon	If true, program runs in foreground and logging is on also on stdout.
level	The lowest level of messages to actually be logged.

Returns

0 if OK, else positive error code.

Definition at line 85 of file lirc_log.c.

void lirc_log_set_file

(

const char *

s

)

Set logfile. Either a regular path or the string 'syslog'; the latter does indeed use syslog(1) instead. Must be called before lirc_log_open().

Definition at line 74 of file lirc_log.c.

int lirc_log_setlevel

(

loglevel_t

level

)

Set the level. Returns 1 if ok, 0 on errors.

Definition at line 161 of file lirc_log.c.

int lirc_log_use_syslog

(

void

)

Check if log is set up to use syslog or not.

Definition at line 68 of file lirc_log.c.

void logperror	(	loglevel_t	prio,
		const char *	fmt,
			...
	)

Prints a description of the last error to the log.

Parameters

prio	Priority of log request.
fmt	printf-style format string

Definition at line 288 of file lirc_log.c.

void logprintf	(	loglevel_t	prio,
		const char *	format_str,
			...
	)

Prints the log request to the log, if the priority fits.

Parameters

prio	Priority of log request
format_str	Format string in the usual C sense.
...	Additional vararg parameters.

Definition at line 242 of file lirc_log.c.

loglevel_t string2loglevel

(

const char *

level

)

Convert a string, either a number or 'info', 'trace1', error etc. to a loglevel.

Definition at line 216 of file lirc_log.c.

Variable Documentation

loglevel_t loglevel = LIRC_NOLOG

The actual loglevel. Should not be changed directly by external code.
