| # Debug IPC |
| |
| This is the shared IPC code between the debug agent (code in |
| [../debug_agent](../debug_agent)) and the zxdb frontend (code in |
| [../zxdb](../zxdb)). It's not useful for other programs. Client debugging code |
| should use the client debug library in [../zxdb/client](.,./zxdb/client). |
| |
| This is a super simple custom IPC format because it is intended to be used |
| between two computers (unlike FIDL) and called at a very low level when |
| debugging the system (when higher-level primitives should be avoided). The |
| goal is to replace it with a more robust IPC library when one is provided for |
| the system that can communicate off-device. |

| ## Protocol information |
| |
| * Structs are defined with sized types and serialized |
| little-endian such that they can be memcpy'd on little-endian machines. |
| |
| * Vectors are serialized as a 32-bit count followed by the number of records |
| serialized in the normal manner. |
| |
| * Strings are serialized as a 32-bit size followed by that number of 8-bit |
| characters. No encoding is specified, the data is not null terminated. |
