Hello,

I'm trying to output an structure array from my S-Function. The data comes from a shared memory which gives an easy access via pointer.

This code didn't work:

static void mdlOutputs(SimStruct *S, int_T tid)
{
    StructType *struct = (StructType *) ssGetOutputPortSignal(S, 0);
    // Info: Outport 0 has a width of 10    
    
    {
        // Access to shared memory  
        scoped_lock<named_mutex> lock(CM_ADTF_mtx); // lock access to shared memory for other processes
        ListType * ShM_List  = managed_shm.find_or_construct<ListType>("CM_ADTF_List")();
        
        memcpy(EnvMdlObj, ShM_objList->EnvMdlObj, 10*sizeof(StructType));
        // also not working:
        // EnvMdlObj[0] = ShM_List->EnvMdlObj[0];
        // EnvMdlObj[1] = ShM_List->EnvMdlObj[1];
    }
} /* end mdlOutputs */
