Function Documentation

void __log	(	char *	srcfile,
		int	srcline,
		const char *	srcfunc,
		char *	fmt,
			...
	)

The internal implementation for logging.

Warning

This function is not intended to be called directly by the user. Use _log() instead, as this macro inserts the correct position of the call to __log().

This function is synchronized internally and therefore may be called by several threads 'at once'.

Parameters

srcfile	The file executing the call to __log(); filled by macro _log(), do not use "by hand"
srcline	The line in the file executing the call to __log(); filled by macro _log(), do not use "by hand"
srcfunc	The function callint __log(); filled by macro _log(), do not use "by hand"
fmt	The format used format the line, see man 3 printf for usage.

Here is the caller graph for this function:

void log_close

(

)

Finalize logging.

Closes any opened descriptors and frees any remaining memory allocated during usage. Any calls to _log() after call to log_close() do not have any effect.

Typically this function is only called prior to termination.

Here is the caller graph for this function:

bool log_init

(

char *

file

)

Initialize logging.

Initialize logging and thus allow subsequent calls to _log().

Typically this function is called only once directly after starting up the execution

Parameters

file	The file to log to, either relative or absolute path.

Returns

true on success, false on error
