Gain of remove_directory

[Grégory Vanuxem]

Hello Waldek, *

I wonder what is the gain of using 'remove_directory' in cfuns-c.c.

Waldek, do you happen to remember why you added its use?

Is there a specific LISP implementation that needs it?

Or is it to avoid some stuff like 'sys exec rm -rf dir' in a hypothetical language?

Regards,

W had discussion in the list starting from 27 Jun 2013.
Basically, one reason is speed: C code is much faster than
starting external program. Another reason is portablity:
C code depends only on fundamental Posix-standarized operations.
Alternatives bring various dependencies which may cause trouble,

Oh, I should have looked in the mailing list archives.

So I guessed wrong, I thought this was implemented to avoid shell calls. So implementation specific.

Thanks
