glXIsDirect 3G
glXIsDirect indicate whether direct rendering is enabled

## C Specification

Bool `glXIsDirect` Display * dpy GLXContext ctx

## Parameters

dpy

  Specifies the connection to the X server.

ctx

  Specifies the GLX context that is being queried.

## Description

`glXIsDirect` returns `True` if ctx is a direct rendering context, `False` otherwise. Direct rendering contexts pass rendering commands directly from the calling process's address space to the rendering system, bypassing the X server. Nondirect rendering contexts pass all rendering commands to the X server.

## Errors

`GLXBadContext` is generated if ctx is not a valid GLX context.
