/* This macro creates the following functions:

|
|
gdbpy_initialize_{NAME}_event
|
|
Used to add the newly created event type to the gdb module.
|
|
|
|
and the python type data structure for the event:
|
|
|
|
struct PyTypeObject {NAME}_event_object_type
|
|
|
|
NAME is the name of the event.
|
|
PY_PATH is a string representing the module and python name of
|
|
the event.
|
|
PY_NAME a string representing what the event should be called in
|
|
python.
|
|
DOC Python documentation for the new event type
|
|
BASE the base event for this event usually just event_object_type.
|
|
QUAL qualification for the create event usually 'static'
