Function Documentation

◆ SCLogAddFDFilter()

int SCLogAddFDFilter ( const char * function )

Adds a Function-Dependent(FD) filter.

Name	of the function for which a FD filter has to be registered

Return values

0	on success
-1	on failure

Definition at line 639 of file util-debug-filters.c.

◆ SCLogAddFGFilterBL()

int SCLogAddFGFilterBL	(	const char *	file,
		const char *	function,
		int	line
	)

Adds a Blacklist(BL) fine-grained(FG) filter. A FG filter BL filter allows messages that don't match this filter, to be logged, while the filter is defined using a file_name, function_name and line_number.

If a particular parameter in the fg-filter(file, function and line), shouldn't be considered while logging the message, one can supply NULL for the file_name or function_name and a negative line_no.

Parameters

file	File_name of the filter
function	Function_name of the filter
line	Line number of the filter

Return values

0	on successfully adding the filter
-1	on failure

Definition at line 333 of file util-debug-filters.c.

Helper function used internally to add a FG filter. This function is called when the file component of the incoming filter has no entry in the filter list.

Parameters

fgf_file	The file component(basically the position in the list) from the filter list, after which the new filter has to be added
file	File_name of the filter
function	Function_name of the filter
line	Line number of the filter
listtype	The filter listtype. Can be either a blacklist or whitelist filter listtype(SC_LOG_FILTER_BL or SC_LOG_FILTER_WL)

void SCLogAddToFGFFuncList	(	SCLogFGFilterFile *	fgf_file,
		SCLogFGFilterFunc *	fgf_func,
		const char *	function,
		int	line
	)

Helper function used internally to add a FG filter. This function is called when the file component of the incoming filter has an entry in the filter list, but the function component doesn't have an entry for the corresponding file component.

Parameters

fgf_file	The file component from the filter list to which the new filter has to be added

void SCLogAddToFGFLineList	(	SCLogFGFilterFunc *	fgf_func,
		SCLogFGFilterLine *	fgf_line,
		int	line
	)

Helper function used internally to add a FG filter. This function is called when the file and function components of the incoming filter have an entry in the filter list, but the line component doesn't have an entry for the corresponding function component.

Parameters

fgf_func	The function component from the filter list to which the new filter has to be added
fgf_line	The function component(basically the position in the list), from the filter list, after which the new filter has to be added
