/* On Windows, a process ID is a DWORD. That might actually be the |

same thing as an int, but it's better not to assume anything. |
| 45 |
|
|
| 46 |
|
This means that we shouldn't rely on PIDs and file descriptors |
| 47 |
|
being the same type, so we have to describe processes with a struct, |
| 48 |
< |
instead of the original int[3]. To keep things simple, we typedef |

< |
the posix pid_t on those systems that don't have it already. |
| 35 |
< |
|
| 36 |
< |
Some older Windows systems use negative PIDs. Open_process() and |
| 37 |
< |
close_process() will convert those to positive values during |
| 38 |
< |
runtime, so that client modules can still use -1 as invalid PID. |
| 48 |

platform independent RT_PID. |
