# glXWaitGL(3x)

complete GL execution prior to subsequent X calls

## NAME

glXWaitGL - complete GL execution prior to subsequent X calls

## C SPECIFICATION

void **glXWaitGL**( void )

```

```

delim $$

## DESCRIPTION

GL rendering calls made prior to **glXWaitGL** are guaranteed to be executed before X rendering calls made after **glXWaitGL**. Although this same result can be achieved using **glFinish**, **glXWaitGL** 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.

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

## NOTES

**glXWaitGL** may or may not flush the X 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is generated if the drawable associated with the current context of the calling thread is a window, and that window is no longer valid.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**, **glXWaitX**, **XSync**
