glXIsDirect Subroutine

OpenGL 1.2 for AIX: Reference Manual

glXIsDirect Subroutine

Purpose

Indicates whether direct rendering is enabled.

Library

OpenGL C bindings library: libGL.a

C Syntax

Bool glXIsDirect(Display *dpy
                 GLXContext Context)

Description

The glXIsDirect subroutine returns a value of True if the Context parameter supplied is a direct rendering context. Otherwise, False is returned. Direct rendering contexts bypass the X server and pass rendering commands directly from the address space of the calling process to the rendering system. Nondirect rendering contexts pass all rendering commands to the X server.

Parameters

dpy	Specifies the connection to the X server.
Context	Specifies the GLX context being queried.

Return Values

True	Returned if Context is a direct rendering context.
False	Returned if Context is not a direct rendering context.

Error Codes

GLXBadContext

Context is not a valid GLX context.
