[Info-vax] Howto can I call the undocumented "set watch/class=dir" in an own program and fetch the output in my program?

Hi,

for my project a need the information, what file operation (i.e. crea/dir or remove file) is been issued from an interactive terminal process.
I've seen that the "undocumented" dcl-command "set watch" just broadcasts this information to the terminal I need. I did look into the source and found that this program only modifies a system parameter called PIO$GW_DFPROT and CLASS_FLAGS[x], where x = XQP$_MAJOR_FUNC, XQP$_CNTRL_FUNC, XQP$_ATTRIBUTE,XQP$_DIR_OPS, XQP$_DUMP, XQP$_QUOTA or XQP$_PROTECTION are accessed.
It is unclear for me if it is possible to get access to these infos in an own written program. So I'm thankful for any ideas where to look at.
