Re: Session Id for program
Below is a c function you can call from 4gl to get the unix process id
(pid). This isn't the session id (which is an informix thing) but it is
also unique.
Example 4gl call:
let filename = "myfile",processid() using "<<<<<<<<"
The c function:
processid(nargs) int nargs;
{
retlong(getpid());
return(1);
}
If you really wanted you could then get the informix session id:
select sid from sysmaster:syssessions where pid = processid()
Best wishes,
