Setting and getting the process name?

Martin Cowie — Thu, 03 Mar 2005 10:51:30 GMT

This is a question from a longtime Unix developer with some degree of VMS understanding.

The C RTL gives me 'getpid()', but how can I get the process *name* instead? Furthermore, can I set my process name, and if so how?

All clues welcomed.

Martin,

Don't have a C routine at hand, but you can always call upon a system service from within a C routine.
The system service SYS$GETJPI[W] can pretty much return any information about the process. For setting the process name you have the system service SYS$SETPRN.

or LIB$GETJPI with the item code JPI$_PRCNAM

This is looking good, however, calling non RTL functions such as $GETJPI is a whole new world to me, and the ample docs you point me at leave me feeling bamboozled.

Could anyone volunteer some example code, that I might how to call this and other system services in ANSI C?

Your clues still welcomed,

M.
