GLXCREATEGLXPIXMAP()UNIX Programmer's Manual GLXCREATEGLXPIXMAP()
glXCreateGLXPixmap - create an off-screen GLX rendering area
GLXPixmap glXCreateGLXPixmap( Display *dpy,
XVisualInfo *vis,
Pixmap pixmap )
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.
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 visi-
ble 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.
XVisualInfo is defined in Xutil.h. It is a structure that
includes visual, visualID, screen, and depth elements.
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.
