strncpy() is an ambiguous and potentially dangerous interface [1]. We should prefer more robust and less ambiguous alternatives. @query is marked as __nonstring and doesn't need to be NUL-terminated. Since we are doing a string to memory copy, we can use the aptly named "strtomem" -- specifically, the "pad" variant to also ensure NUL-padding throughout the destination buffer.
