memory block -> C++ strings


I have a large block of memory. I need to (1) check if it contains only
ASCII characters (including newlines and/or carriage-returns) and, if so,
(2) extract the lines into individual C++ strings.

Currently I loop the entire block (byte for byte), run isascii(byte) on each
byte, and then call getline() (either string.getline or iostream.getline
does the job). This is proving too slow. I'm sure this problem has been
solved using more efficient methods. Any suggestions?
