/* On Windows, a process ID is a DWORD. That might actually be the |
| 30 |
|
same thing as an int, but it's better not to assume anything. |
| 31 |
|
|
| 32 |
|
This means that we shouldn't rely on PIDs and file descriptors |
| 33 |
|
being the same type, so we have to describe processes with a struct, |
| 34 |
< |
instead of the original int[3]. To keep things simple, we typedef |
| 35 |
< |
the posix pid_t on those systems that don't have it already. |
| 38 |
< |
|
| 39 |
< |
Some older Windows systems use negative PIDs. Open_process() and |
| 40 |
< |
close_process() will convert those to positive values during |
| 41 |
< |
runtime, so that client modules can still use -1 as invalid PID. |
| 34 |
> |
instead of the original int[3]. For that purpose, we typedef a |
| 35 |

platform independent RT_PID. |
