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. |
33 |
< |
|
34 |
< |
Some older Windows systems use negative PIDs. Open_process() and |
35 |
< |
close_process() will convert those to positive values during |
36 |
< |
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. |
