c to rpg

["Brendan Bispham" <midrangel@xxxxxxxxxxxxxxxxxx>]

Hi,
Im using the MATMATR example to retrieve the serial number, but I dont
understand how C returns parameters (to my RPG module):

The C program has int main(void) {

I know I can access incoming arguments with arg[] but how do I return the
serial number (and anything else) as a parm... I think I have to replace the
"void" with one or more parms

Has anyone got any pointers I can reference...

TIA,

nb example code i'm looking at is:
#include <QSYSINC/MIH/MATMATR>
#include <stdio.h>
 _MMTR_Template_T    machine_attributes;
 int main(void)

 machine_attributes.Options.Template_Size = 16;
  matmatr( &machine_attributes,  _MMTR_SERIAL );
   printf("Serial Number of this AS/400 is: %8.8s \n",
             machine_attributes.Options.Data.Serial );
  }
