NAME
     glXCreatePixmap - create an off-screen rendering area


C SPECIFICATION
     GLXPixmap glXCreatePixmap( Display *dpy,
                                GLXFBConfig config,
                                Pixmap pixmap,
                                int *attrib_list )


PARAMETERS
     dpy          Specifies the connection to the X server.

     config       Specifies a GLXFBConfig structure with the desired
                  attributes for the rendering area.

     pixmap       Specifies the X pixmap to be used as the rendering area.

     attrib_list  Currently unused. This must be set to NULL, or be an empty
                  list (i.e., one in which the first element is None).

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

NOTES
     glXCreatePixmap is available only if the GLX version is 1.3 or greater.

     If the GLX version is 1.1 or 1.0, the GL version must be 1.0.  If the GLX
     version is 1.2, then the GL version must be 1.1.  If the GLX version is
     1.3, then the GL version must be 1.2.

ERRORS
     BadMatch is generated if pixmap was not created with a visual that
     corresponds to config.

     BadPixmap is generated if pixmap is not a valid pixmap.
     BadAlloc is generated if the X server cannot allocate a new GLX pixmap.

     GLXBadFBConfig is generated if config is not a valid GLXFBConfig.
