constants
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 _spawn is asynchronous. |
