I would prefer an interface without null pointers in arguments. This
is completely a taste issue.
how about
getTextZ(w, buf)
?

If one asked about null-terminated string, zero should be treated as the terminator.
If one didn't, then it is an error and should be flagged as such.
Imagine off-by-one; it will never be caught untill too late if it just stops.
