| A simple client to make GDB (versions 4.4 and later) on Mach 3 return |
| to the command level when it is waiting for the inferior to stop. |
| |
| Actions: Lookup the send right to the GDB message port from the |
| NetMsgServer. |
| |
| Send an asynchronous message with msgh_id |
| GDB_MESSAGE_ID_STOP to that port. |
