| 29 | * REASONS WHY NINDY CAN STOP EXECUTING AN APPLICATION PROGRAM | |
| 30 | * | |
| 31 | * When NINDY stops executing an application program that was running | |
| 32 | * under remote host ("gdb") control, it signals the host by sending | |
| 33 | * a single ^P. The host can then query as to the reason for the halt. | |
| 34 | * NINDY responds with two bytes of information. | |
| 35 | * | |
| 36 | * The first byte is a boolean flag that indicates whether or not | |
| 37 | * the application has exited. | |
| 38 | * | |
| 39 | * If the flag is true, the second byte contains the exit code. | |
| 40 | * | |
| 41 | * If the flag is false, the second byte contains a "reason for | |
| 42 | * stopping" code. This file defines the possible values of that | |
| 43 | * code. | |
| 44 | * | |
| 45 | * There are three categories of reasons why the halt may have occurred: | |
| 46 | * faults, traces, and software interactions. The first two categories | |
| 47 | * are processor-dependent; the values of these codes are tightly coupled | |
| 48 | * to the hardware and should not be changed without first examining | |
| 49 | * src/nindy/common/fault.c. The software interactions involve | |
| 50 | * communication between NINDY and the host debugger; their codes are | |
| 51 | * arbitrary. | |
