# XPresentNotifyMSC(3)

X Present Extension

## NAME

XPresentNotifyMSC - X Present Extension

## SYNTAX

\#include \<X11/extensions/Xpresent.h\>

```

void XPresentNotifyMSC (Display *display,
	Window window,
	uint32_t serial,
	uint64_t target_msc,
	uint64_t divisor,
	uint64_t remainder);
```

## DESCRIPTION

**XPresentNotifyMSC** requests that the X server specified by *display* deliver a **PresentCompleteNotifyEvent** with kind **PresentCompleteKindNotifyMSC** after the time specified by *target-msc*, *divisor* and *remainder*.

*serial* is an arbitrary client-specified value which will be returned in the event so that the client can associate the event and request.

If *target-msc* is greater than the current Media Stream Counter (msc) for *window*, the event will be delivered at (or after) the *target-msc* field. Otherwise, the event delivery will occur after the next field where msc % *divisor* == *remainder*.

If *window* is destroyed before the event is delivered, then the event delivery will not be completed.
