Problem with matctx supported interface

Hi all,

I'm trying to write a utility to display changed
objects. It is mainly in rpg and call c for the
qusmatarializecontext api (didnt want to use system
pointers in rpg).

I didnt want to use mi since matctx is not directly
supported.

So the rpg creates a user space manges the selection
structure and call the c module. This is the c module:
/**************************************************************/
    
/* This program is used to materialize context with

/* interface.

/* Parms:

/*        Pointer to space for materialization

lib_ptr = rslvsp(_Library, prlib, "QSYS",

                           Options);                  
         
         }                                            
         

The c program does not work and i get :

Thanks for helping a begginer
