Syntax
struct FProcState
Remarks
Wrapper around Unix pid_t. Should not be copyable as changes in the process state won't be properly propagated to all copies.

bool | bFireAndForget | Whether this child is fire-and-forget |
 |
bool | bHasBeenWaitedFor | Whether the process's return code has been collected |
 |
bool | bIsRunning | Whether the process has finished or not (cached) |
 |
pid_t | ProcessId | Process id |
 |
int32 | ReturnCode | Return code of the process (if negative, means that process did not finish gracefully but was killed/crashed |
