Hi,

I've already  wrote what you need : mangling argc argv

the following parseCommandLine method parse the main argc argv and update
the class member
m_nOrbArgc  and m_nOrbArgv that will be passed to ORB_init

Hope it helps


void CorbaClient::parseCommandLine(int argc, char *argv[])
// Parse the command line and look for -ORB args.
// If no -ORBpoa_iiop_port exist, append the argument -ORBpoa_iiop_port
<m_nINSPOAPortNumber>
// in <m_OrbArgv> and update <m_nOrbArgc>.
// If the Import/Export mode is not ExM_INSPOA, m_OrbArgv and m_OrbArgc are
initialized with
// argv and argc.
// Note: argc and argv are unchanged
{
 // The new argv, argc are initialised with the actual argv, argc values
 m_OrbArgv = argv;
 m_nOrbArgc = argc;


 if (m_ImportExportMode == ExM_INSPOA)
 {
  //
  // Look for -ORB arguments
  //
  bool bParamAlreadyExist = false;

  int idx = 1;
  while (argc > idx)
  {
   // -ORBxxxxxxx ?
   if (strlen(argv[idx]) < 4 ||
    !(argv[idx][0] == '-' && argv[idx][1] == 'O' &&
    argv[idx][2] == 'R' && argv[idx][3] == 'B'))
   // This is not an -ORB argument
   {
    // Go to next argument
    idx++;

    continue;
   }

   //
   // Standard options
   //
   //
   // -ORBpoa_iiop_port
   //
   if( strcmp(argv[idx],"-ORBpoa_iiop_port") == 0 )
   {
    if( (idx+1) >= argc )
    {
     cerr << "CorbaClientServer::Create failed -- missing -ORBpoa_iiop_port
parameter." << endl;
     break;
    }

    unsigned port;
    if( sscanf(argv[idx+1], "%u", &port) != 1 ||
     (port == 0 || port >= 65536) )
    {
     cerr << "CorbaClientServer::Create failed -- invalid -ORBpoa_iiop_port
parameter." << endl;
     break;
    }

    // The -ORBpoa_iiop_port argument exist and is valid
    bParamAlreadyExist = true;

    break;
   }

   // Go to next argument
   idx++;
  }



  //
  // Append -ORBpoa_iiop_port <m_nINSPOAPortNumber>
  //
  if (!bParamAlreadyExist)
  {
   // Create 2 arguments
   // * -ORBpoa_iiop_port
   // * "m_nINSPOAPortNumber"
   char *szArg[2] = {"-ORBpoa_iiop_port", NULL};
   char szNumPort[10];
   sprintf(szNumPort, "%d", m_nINSPOAPortNumber);
   szArg[1] = strdup(szNumPort);

   int addedArgc = sizeof(szArg) / sizeof(char *);
   m_nOrbArgc += addedArgc;

   // allocate a new entry in the string array
   m_OrbArgv = (char**)malloc(m_nOrbArgc*sizeof(char*));
   m_bArgvAllocated = true;

   // allocate each string and recopy argv[i] to newargv[i]
   int i;
   for (i = 0; i < argc; i++)
    m_OrbArgv[i] = strdup(argv[i]);

   // append the -ORBpoa_iiop_port arg
   for (int j = i; j < m_nOrbArgc; j++)
    m_OrbArgv[j] = strdup(szArg[j - i]);

   // destroy the duplicated string because it is no more needed
   // and already duplicated in m_OrbArgv.
   delete szArg[1];

  } // End if (!bParamAlreadyExist)

 } // End if (m_ImportExportMode == ExM_INSPOA)
}
