int explain_buffer_get_current_directory	(	explain_string_buffer_t *	sb,
		char *	data,
		size_t	data_size
	)

The explain_buffer_get_current_directory function may be used to obtain the path of the current directory, printing errors as and when they are found.

Parameters:

sb	The string buffer to print into.
data	The buffer to place the generated path into, once found
data_size	The siz eof the buffer, in bytes.

Returns:

int; 0 in success (path found, no errors), or -1 when path not found and message already printed.

static int recursive_pwd	(	explain_string_buffer_t *	sb,
		explain_string_buffer_t *	dot,
		const struct stat *	dot_st,
		explain_string_buffer_t *	result
	)		[static]

The recursive_pwd function is used to recursively walk up the ".." chain until "/" is reached, and then glue on the discovered directory entry names as it unwinds.

Parameters:

sb	The string buffer to print error messages into.
dot	The string buffer to build the ".." chain into.
dot_st	The file status information of the drectory entry to search ".." for.
result	The constructed pathname as parent names are discovered.

Returns:

int; 0 if a path was found, -1 if no peth could be found AND an error message has already been printed.
