GLXCREATEGLXPIXMAP()					  GLXCREATEGLXPIXMAP()

NAME
       glXCreateGLXPixmap - create an off-screen GLX rendering area

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

       delim $$

PARAMETERS
       dpy     Specifies the connection	to the X server.

       vis     Specifies  the visual that defines the structure	of the render-
	       ing 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 vi-
       sual, 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  vi-
       sual).

       BadPixmap is generated if pixmap	is not a valid pixmap.

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