FYI, malloc(3) is actually a library call, and while it obviously does invoke

Yes, it's supposed to segfault. Check out what, say, strcpy does if
you ask it to copy a NULL pointer. And this is an improvement from the
bad old days, when they would happily walk through memory starting at
0.
Besides, errno is used to signal errors from system calls. strdup
isn't a system

Hi,
I recently had to tell someone that strncpy does not always zero terminate
the destination string. Surprised by what I was telling they immediately
wanted to change the way the function worked. When a function is defined by
an ISO standard you are not supposed to change the definition.
