Hi,
I am trying to see if there is a way to determine if a program is in the
path (i.e. a bit like "which"), returning a #t or #f answer. I was
looking execl and execlp.
The documentation for execl says:
> Executes the file named by path as a new process image
what is path ? I'm guessing that that should be "filename".
While playing around, I notice that
(execlp "ls")
produces a core dump.
My question is then, *is* there a way to determine if a string is
executable? (And if so, how? :-)
Thanks,
Paul.
