Calling RPG program from ILE-C

I asked this question once a year ago, but an answer stayed unclear for me.

The problem is following:
My C program must call an RPG program (e.g. PROGA), that can be in one of the 2 
libraries (or in both) KLIB123 or KAPBASELIB.
If program is in KLIB123, I must call it even if it is also in KAPBASELIB. If 
it is missing in KLIB123, a version from KAPBASELIB must be called.
These 2 libraries are in proper order in library list - KLIB123 is before 
KAPBASELIB.

Now what I do :

#pragma map(action, "PROGA")
#pragma linkage(action, OS)
void action (......)

int main()
{
  .....
  action (...) ;
  .....
}

This DOES NOT work.
If I put 
#pragma map(action, "KLIB123/PROGA")
and PROGA is in KLIB123, it works. But if PROGA is in KAPBASELIB - it does not 
work.

If I put 
#pragma map(action, "*LIBL/PROGA")
it never works.

I thought, that the thread does not have proper library list (The program is 
called from PC via another program (H56HSR)). I used QWCRTVCA to get a current 
library list and it is correct, containing KLIB123 and KAPBASELIB in proper 
order.

Is there any way to call RPG program as a function using library list?
Or maybe I'm doing something wrong?
