11 | // On Windows the GetExitCodeProcess API is used to get the exit code of a | |
12 | // process, but it's easy to mistake a process exiting with the code 259 as | |
13 | // "still running" because this is the value of the STILL_ACTIVE constant. Make | |
14 | // sure we handle this case in the standard library and correctly report the | |
15 | // status. | |
16 | // | |
17 | // Note that this is disabled on unix as processes exiting with 259 will have | |
18 | // their exit status truncated to 3 (only the lower 8 bits are used). | |
