Hi,

Why is this needed in csound.c?

#ifdef never
void PUBLIC sigcpy(MYFLT *dest, MYFLT *src, int size)
{                           /* Surely a memcpy*/
    memcpy(dest, src, size*sizeof(MYFLT));
}
#endif

I don't see the never macro defined anywhere...

Cheers,
Andrés

Precisely, never is never defined.

I use it to remove code that I do not want to lose.  Istvan used "#if 0"
for this must I like never and somefineday

I still tend to use #ifdef NOTDEF, which I picked up decades ago from 
CDP's first system programmer Martin Atkins. Istvan's form is unarguably 
"logical", but it is not a symbol that one can really search for!

Note that git (unlike cvs) is very good at looking for deleted code,
so there is no real need to #ifdef never.

git log -Ssigcpy will look for commits that touch a line containing sigcpy

You can use the --since and --until options if needed. After that you
can use git show to actually see what the commit did.

I agree with Felipe, and I think it is a good idea to write code that
contains nothing that does not execute. The code should be as clear
and easy to read as possible, without distractions, and that means a
minimum of comments (also potentially confounding) also.

Regards,
Mike

In the case in question I was unsure that the function was not used and
restoring could be necessary.  My confidence in git is not that strong as
it screws up 3 or 4 times a week.
