Function Documentation

err_get_logfp()

FILE * err_get_logfp

(

void

)

Get the current logging filehandle.

Returns

Current logging filehandle, NULL if logging is disabled. Initially it returns stderr

Definition at line 267 of file err.c.

err_logfp_cb()

void err_logfp_cb	(	void *	user_data,
		err_lvl_t	lvl,
		const char *	fmt,
			...
	)

Definition at line 224 of file err.c.

err_msg()

void err_msg	(	err_lvl_t	lvl,
		const char *	path,
		long	ln,
		const char *	fmt,
			...
	)

Definition at line 81 of file err.c.

err_msg_system()

void err_msg_system	(	err_lvl_t	lvl,
		const char *	path,
		long	ln,
		const char *	fmt,
			...
	)

Definition at line 158 of file err.c.

err_set_callback()

void err_set_callback	(	err_cb_f	callback,
		void *	user_data
	)

Sets function to output error messages.

Use it to redirect the logging to your application. By default the handler which dumps messages to stderr is set.

Parameters

callback	callback to pass messages too
user_data	data to pass to callback

Definition at line 278 of file err.c.

err_set_logfile()

int err_set_logfile

(

const char *

path

)

Append all log messages to a given file.

Previous logging filehandle is closed (unless it was stdout or stderr).

Parameters

path	File path to send log messages to

Returns

0 for success, <0 for failure (e.g. if file does not exist)

Definition at line 240 of file err.c.

err_set_logfp()

void err_set_logfp

(

FILE *

stream

)

Direct all logging to a given filehandle if default logfp callback is set.

Parameters

stream

Filehandle to send log messages to, or NULL to disable logging.
