sys$forcex

Can someone do me a huge favor and write a quick little C program to request the process id and do a $forcex on that process.

OpenVMS 8.3-1h1

The last link had just the program I was looking for.

Whoops. Forgot one.

$ STOP /IMAGE /ID=pid
$ STOP /IMAGE prcnam

No compiler needed.

James,

Note that since V7.3 the default for STOP is /EXIT, which invokes exit handlers of the target process, but the process is still terminated. This removes some of the dangers of the STOP command. As Hoff said, there is also the /IMAGE qualifier to only issue a $FORCEX to the target process, so it may continue after exitting the current image.

(it took me more than 10 years of lobbying and pestering to get this implemented, but it finally paid off... ;-)
