No, they could simply return sizeof(buf) + 1 and have the same effect. Running through the whole length of the string that would have been created is potentially non-useful [sic]. It also potentially slows strlcat() down, particularly is some programmers start to rely on its behaviour to find the new amount of memory needed to allocate instead of doing the math themselves. -- This is my .signature which gets appended to the end of my messages.
