Return value of snprintf(): 13

correct

Now, I'm not sure if the return value of snprintf() is supposed to be 6
or 13 in this case. I'd say the return value of snprintf() should always
be the same of that returned by strlen()....

incorrect ...

you're confusing the points at which the string is evaluated as a string ... snprintf is writing the given format string based upon the arguments ...

embedded null characters in the format string matter, arguments given via output specifiers do not matter
ok; thus in conclusion the current behaviour of snprintf() is the correct one...

Thanks!
