Gets the raw status code of the process, as from waitpid
.
This value has no particular meaning, but it can be used with the macros defined by the system headers such as WIFEXITED. It can also be used with check_wait_status.
It is more likely that you want to use get_if_exited followed by get_exit_status.
It is an error to call this function before wait has returned.
