Function Documentation

◆ check_path_exists()

int check_path_exists	(	const char *	path,
		mode_t	type,
		mode_t	mode
	)

Check the existence, type and permissions of a path.

Parameters

[in]	path	Pointer to a string representing the path.
[in]	type	The type the path should be (0 disables this check).
[in]	mode	Type of access the path should have (0 disables this check).

Returns

return value

0 the path exists and has at least the requested permissions
-1 the path does not exists or has not the requested permissions
