function content_add_new_uploaded_file

7.x content.module content_add_new_uploaded_file($file, $cid = 0, $bool_override_original_filename = TRUE, $attributes = CONTENT_PRIVATE_FILE, $bool_replace_exsting_filename = FALSE)
6.x content.module content_add_new_uploaded_file($file, $cid = 0, $bool_override_original_filename = TRUE, $attributes = CONTENT_PRIVATE_FILE, $bool_replace_exsting_filename = FALSE)

bool_replace_existing means should we replace an existing file (based on filename) with this new one? Instead of creating an INSERT, that is.
