Re: ExtProc('stat') and a timeout

Let's see - documentation says it returns an integer

int access(const char /*path/, int /amode/);


It returns 0 if your test is good. path is a regular character 
variable, null-terminated - can use something like what you have with 
stat. amode is by value, integer again. To test for existence, set amode 
= 0.

That'll give you what you need.
