If you're interested, openpam_readword(3) implements the full POSIX
shell quoting rules, including line continuations and multi-line quoted
strings, and should be fairly easy to translate to C++.  There is also
an openpam_readlinev(3) which reads a full line (or more in case of line
continuations) and returns an array of words.  Obviously, you'll want to
copy & adapt them rather than link devd with libpam.
