| /// @assertion Future<int> exitCode |
| /// |
| /// Returns a Future which completes with the exit code of the process when the |
| /// process completes. |
| /// |
| /// The handling of exit codes is platform specific. |
| /// |
| /// On Linux and OS X a normal exit code will be a positive value in the range |
| /// 0..255. If the process was terminated due to a signal the exit code will be |
| /// a negative value in the range -255..-1, where the absolute value of the exit |
| /// code is the signal number. For example, if a process crashes due to a |
| /// segmentation violation the exit code will be -11, as the signal SIGSEGV has |
| /// the number 11. |
| /// |
| /// On Windows a process can report any 32-bit value as an exit code. When |
| /// returning the exit code this exit code is turned into a signed value. Some |
| /// special values are used to report termination due to some system event. E.g. |
| /// if a process crashes due to an access violation the 32-bit exit code is |
| /// 0xc0000005, which will be returned as the negative number -1073741819. To get |
| /// the original 32-bit value use (0x100000000 + exitCode) & 0xffffffff. |
| /// |
| /// @description Checks that [exitCode] returns a Future which completes with the |
| /// exit code of the process when the process completes. On Linux and OS X a |
| /// normal exit code will be a positive value in the range 0..255. |
