fix incorrect usage of strncpy() to (an internal implementation of) estrlcpy().
void
estrlcpy(char *dst, char *src, size_t len)
{
if (strlcpy(dst, src, len) >= len) {
errno = ENAMETOOLONG;
err(1, "Cannot copy `%s'", src);
}
}
This seems to be a bit of a pun on ENAMETOOLONG, which is defined (by SUS and us) to be filename-specific, and to mean precisely that a component of a pathname exceeded NAME_MAX(resp. MAXNAMELEN) or that the entire path exceeded PATH_MAX(resp. MAXPATHLEN-1). Obviously the function doesn't return, so it isn't a matter of misleading the caller, but it will still print the message "File name too long" which is a little odd and could send a user down the wrong track trying to figure out why the utility might have failed. Would it be bad to use errx and a specific message? -Chap
