Syntax
#include <process.h>
Remarks
The mode argument determines the action taken by the calling process before and during a spawn operation. The following values for mode are possible:
| Constant | Meaning |
|---|---|
_P_OVERLAY |
Overlays calling process with new process, destroying calling process (same effect as _exec calls). |
_P_WAIT |
Suspends calling thread until execution of new process is complete (synchronous _spawn). |
_P_NOWAIT, _P_NOWAITO |
Continues to execute calling process concurrently with new process (asynchronous _spawn). |
_P_DETACH |
Continues to execute calling process; new process is run in background with no access to console or keyboard. Calls to _cwait against new process will fail. This is an asynchronous _spawn. |
