Class DD_Exception: Exceptions that can be thrown by the DD system calls. A DD exception consists of an error message, which is given by a static const char* variable. The errorcodes are enumerated and the array of error messages is sized to NUM_ERRORS+1 in order to handle an iCode which is invalid (i.e. > NUM_ERRORS).

The typical use of the code is:

   DD *my_dd;
   try {
     my_dd = pDDfactory->create_dd( dd_name, "w", dd_config_file );
   } catch ( DD_Exception &ex ) {
     cout << "Exception raised while creating DD system " << dd_name << endl;
     ex.print();
     delete &ex;
     exit(EXIT_FAILURE);
   }  
   

Note that the entire DD code can be compiled with -DDD_NOEXCEPTION, in which case no exceptions are present to allow backwards compatibility with older compilers such as IRIX 5.3.

Parameters:
