A simple client to make GDB (versions 4.4 and later) on Mach 3 return
|
| 24 |
|
|
to the command level when it is waiting for the inferior to stop.
|
| 25 |
|
|
|
| 26 |
|
|
Actions: Lookup the send right to the GDB message port from the
|
| 27 |
|
|
NetMsgServer.
|
| 28 |
|
|
|
| 29 |
|
|
Send an asynchronous message with msgh_id
|
| 30 |
|
|
GDB_MESSAGE_ID_STOP to that port.
