Function cef_delete_file 

pub unsafe extern "C" fn cef_delete_file(
    path: *const cef_string_t,
    recursive: c_int,
) -> c_int

Deletes the given path whether it’s a file or a directory. If |path| is a directory all contents will be deleted. If |recursive| is true (1) any sub- directories and their contents will also be deleted (equivalent to executing “rm -rf”, so use with caution). On POSIX environments if |path| is a symbolic link then only the symlink will be deleted. Returns true (1) on successful deletion or if |path| does not exist. Calling this function on the browser process UI or IO threads is not allowed.
