spawn Constants

#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.
