The common method to determine a executable file is stat:perms, you may check it out in the manual for details.

(execlp "ls" "") will access.
Since the second parameter is optional, scm_execlp doesn't handle exec_argv unbounded situation.

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.
