_WriteBarrier
This function forces all previous memory write operations to complete before any subsequent write operation is started.
void __cdecl _WriteBarrier(void);
Parameters
None.
Return Values
None.
Remarks
This function is usually used for writing device drivers to make sure that a set of commands has been sent to the device before further commands are issued. The compiler will not reschedule memory writes across an invocation of _WriteBarrier, even on platforms without explicit synchronization instructions.
Requirements
OS Versions: Windows CE .NET 4.0 and later.
Header: Cmnintrin.h.
