The morality of string delimiters vs. character counts is a debate that has been going on for some 40 years! Some things never change... ;-) Bob Braden
... I think the use of explicitly encoded length, rather than special terminator or deliminator sequences, is simpler to code and debug, as well as being more robust in avoiding buffer overflow problems, etc.

Reserving NUL as a special terminator is a C library-ism. I think that history has shown that the use of this kind of mechanism, rather than explicitly tracking the string's length, was a mistake. Randy
