Python in a Nutshell

Name

PyErr_NewException

Synopsis

PyObject* PyErr_NewException(char* name,PyObject* base,PyObject* dict)

Subclasses exception class base, with extra class attributes and methods from dictionary dict (normally NULL, meaning no extra class attributes or methods), creating a new exception class named name (string name must be of the form "modulename.classname“) and returning a new reference to the new class object. When base is NULL, uses PyExc_Exception as the base class. You normally call this function during initialization of a module object module. For example:

PyModule_AddObject(module, "error", 
    PyErr_NewException("mymod.error", NULL, NULL));
