No time at all, because I'm not going to waste my time re-writing
standard library functions. (Yes, I'm sure I could do it.)
Try changing your compiler's settings. How long did *that* take?
But I'd like to ask others here to confirm your observations.
Other uses of Microsoft Visual Studio: If you compile a simple
program that calls strcpy() with default settings, does it really
treat it as a fatal error?
My suspicion, Malcolm, is that you've modified the settings in
Visual Studio to perform stricter checking than the out-of-the-box
default, and that the actual default behavior is to issue a warning,
not a fatal error.
And again, if you want the functionality of strcpy(), the sensible
way to get it is to disable the deprecation check (which apparently
is quite easy to do), not to write your own version. If you're
unwilling to disable the deprecation check for security reasons,
then you should be unwilling to use mystrcpy(), which at best is
no safer than strcpy().
