GLXCREATEGLXPIXMAP(3G)		 OpenGL Manual		GLXCREATEGLXPIXMAP(3G)

NAME
       glXCreateGLXPixmap - create an off-screen GLX rendering area

C SPECIFICATION
       GLXPixmap glXCreateGLXPixmap(Display * dpy, XVisualInfo * vis,
				    Pixmap pixmap);

PARAMETERS
       dpy
	   Specifies the connection to the X server.

       vis
	   Specifies the visual that defines the structure of the rendering
	   area. It is a pointer to an XVisualInfo structure, not a visual ID
	   or a pointer to a Visual.

       pixmap
	   Specifies the X pixmap that will be used as the front left color
	   buffer of the off-screen rendering area.

DESCRIPTION
       glXCreateGLXPixmap creates an off-screen rendering area and returns its
       XID. Any GLX rendering context that was created with respect to vis can
       be used to render into this off-screen area. Use glXMakeCurrent() to
       associate the rendering area with a GLX rendering context.

       The X pixmap identified by pixmap is used as the front left buffer of
       the resulting off-screen rendering area. All other buffers specified by
       vis, including color buffers other than the front left buffer, are
       created without externally visible names. GLX pixmaps with
       double-buffering are supported. However, glXSwapBuffers() is ignored by
       these pixmaps.

       Some implementations may not support GLX pixmaps with direct rendering
       contexts.

NOTES
       XVisualInfo is defined in Xutil.h.  It is a structure that includes
       visual, visualID, screen, and depth elements.

ERRORS
       BadMatch is generated if the depth of pixmap does not match the depth
       value reported by core X11 for vis, or if pixmap was not created with
       respect to the same screen as vis.

       BadValue is generated if vis is not a valid XVisualInfo pointer (for
       example, if a particular GLX implementation does not support this
       visual).

       BadPixmap is generated if pixmap is not a valid pixmap.

       BadAlloc is generated if the server cannot allocate the GLX pixmap.
