X Present Extension

## NAME

Xpresent - X Present Extension

## SYNTAX

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

```

Bool XPresentQueryExtension (Display *dpy, int *major_opcode_return,
	int *event_base_return, int *error_base_return);

Status XPresentQueryVersion (Display *dpy,
	int *major_version_return,
	int *minor_version_return);

int XPresentVersion (void);
```

## ARGUMENTS

- *dpy*

  Specifies the connection to the X server.

## DESCRIPTION

**Xpresent** is a library designed to interface the X Present Extension. The Present extension provides a way for applications to update their window contents from a pixmap in a well defined fashion, synchronizing with the display refresh and potentially using a more efficient mechanism than copying the contents of the source pixmap.

The **XPresentQueryExtension** function checks if the X server specified by *dpy* supports the X Present extension. If the server does not support the extension, it returns **False**. If the server does support the extension, it returns **True**, and sets the values of *major\_opcode\_return*, *event\_base\_return*, and *error\_base\_return* if the pointers are not NULL.

Clients must call the **XPresentQueryExtension** function to verify the server supports the extension before calling any other function for this extension.

The **XPresentQueryVersion** function sets the values pointed to by *major\_version\_return* and *minor\_version\_return* to the version of the extension supported by the X server specified by *dpy*. The **XPresentQueryVersion** function returns the version of the libXpresent library in use, as defined by the **PRESENT\_VERSION** macro in \<X11/extensions/Xpresent.h\>.
