IDL System Variables from C [message #22692]

Can one access the definition of a random "system variable" from C?

My IDL code defines a system variable, say !FOO, using DefSysV. I
then want to read !FOO's value from C/DLM code.

This doesn't appear to be possible. The likely candidates don't work:

IDL_GetVarAddr("!FOO") returns NULL.

IDL_FindNamedVariable("!FOO", 0) returns a VPTR... to an UNDEF variable.

A search for "sysv" in export.h doesn't find anything apropos.

I'm stumped. Any suggestions?

Thanks,
^E
