glXCreateGLXPixmap()					  glXCreateGLXPixmap()

NAME
       glXCreateGLXPixmap - create an off-screen GLX rendering area

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

PARAMETERS
       Specifies  the  connection  to the X server.  Specifies the visual that
       defines the structure of the rendering area. It is a pointer to an XVi‐
       sualInfo	 structure,  not a visual ID or a pointer to a Visual.	Speci‐
       fies 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 cre‐
       ated without externally visible names.  GLX pixmaps with double-buffer‐
       ing 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  vis‐
       ual).

       BadPixmap is generated if pixmap is not a valid pixmap.

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