I don't understand the point of strlcpy() and strlcat() return value though. Can it really be used for anything else than checking if the value was truncated? Why not simply return -1 when it is?

if (strocpy(dest, src, sizeof(dest)) < 0) { ... }

vs.

if (strlcpy(dest, src, sizeof(dest)) >= sizeof(dest)) { ... }

Even worse if the size parameter is anything more complicated. Received on Thu Jan 30 12:29:08 2003
