# glXWaitX(3x)

complete X execution prior to subsequent GL calls

## NAME

glXWaitX - complete X execution prior to subsequent GL calls

## C SPECIFICATION

void **glXWaitX**( void )

```

```

delim $$

## DESCRIPTION

X rendering calls made prior to **glXWaitX** are guaranteed to be executed before GL rendering calls made after **glXWaitX**. Although the same result can be achieved using **XSync**, **glXWaitX** does not require a round trip to the server, and it is therefore more efficient in cases where client and server are on separate machines.

**glXWaitX** is ignored if there is no current GLX context.

## NOTES

**glXWaitX** may or may not flush the GL stream.

## ERRORS

**GLXBadCurrentWindow** is generated if the drawable associated with the current context of the calling thread is a window, and that window is no longer valid.

## SEE ALSO

**glFinish**, **glFlush**, **glXWaitGL**, **XSync**
