[C400-L] calling RPG/ILE subprocedure

[sublime78ska@xxxxxxxxx]

Is it possible to call from a C pgm an ILE/RPG subprocedure which returns a 20
position character?  When it returns I get a pointer error.  I tried returning
the address with %addr(filename), which didn't end in error but the value wasn't
correct.

Here's the c pgm:

 char * getHist(char[], const char[]);

 #pragma map(getHist, "GETHIST")

 void main(void)
 {
    char *filename = "\0";

    strcpy(isodate, "2003-02-01");
    filename = getHist(isodate, "OCT");

    return;
 }

here's the rpg procedure:

P getHist            b                   export

D getHist         pi            20  
D  date                           d   datfmt(*iso)
D  filemon                       3    const
D
D filename        s             20

C                   eval      filename='FILEONE   FILETWO'
C
C                   return    filename
P                 e

I appreciate any help you can give!

Thanks,

Phil
