Detailed Description

Somewhat antiquated logging and error interface.

Definition in file err.c.

Function Documentation

int err_get_debug_level

(

void

)

Get debugging verbosity level.

Note that debugging messages are only enabled when compiled with -DDEBUG.

Definition at line 287 of file err.c.

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 268 of file err.c.

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 293 of file err.c.

int err_set_debug_level

(

int

level

)

Set debugging verbosity level.

Note that debugging messages are only enabled when compiled with -DDEBUG.

Parameters

level

Verbosity level to set, or 0 to disable debug messages.

Definition at line 279 of file err.c.

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 241 of file err.c.

References err_get_logfp(), and 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.
