Hi, Todd and Theo!
I wrote this function this week, based on strlcpy(3) and strecopy()[1],
which are the best string copy functions I've seen so far. But I came
to improvements that bring one function that I think is better than both
of those.
I posted the function for review on

As the manual pages says, SUSv2 marked it as LEGACY, and POSIX doesn't

Hi,
I don't know if OpenBSD has a different implementation of alloca(3) than
Linux. In Linux, alloca(3) (a.k.a. __builtin_alloca()) can't return
NULL, as it can't detect errors. The only way to detect an error is to
add a handler for SIGSEGV, AFAIK.
I found the following code in :

The other use is where you want a sequence of:
len *= str_copy(dest + len, dest_len - len, src);
But don't really want to test for overflow after each call.
This is a legitimate use of strscpy(). Please, add it to glibc

I added a few FreeBSD CCs that I found on their tee.c's git blame,
because the freebsd list rejects external mail.
Please have a look at the proposal below, and the discussion that
started on gnu coreutil's list.
