GLXGETVISUALFROMFBCO(3G)					   OpenGL Manual					  GLXGETVISUALFROMFBCO(3G)

NAME

       glXGetVisualFromFBConfig - return visual that is associated with the frame buffer configuration

C SPECIFICATION

       XVisualInfo * glXGetVisualFromFBConfig(Display * dpy, GLXFBConfig config);

PARAMETERS

       dpy
	   Specifies the connection to the X server.

       config
	   Specifies the GLX frame buffer configuration.

DESCRIPTION

       If config is a valid GLX frame buffer configuration and it has an associated X Visual, then information describing that visual is returned;
       otherwise NULL is returned. Use XFree to free the data returned.

NOTES

       glXGetVisualFromFBConfig 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.

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

ERRORS

       Returns NULL if config is not a valid GLXFBConfig.

NAME

       glXCreatePixmap - create an off-screen rendering area

C SPECIFICATION

       GLXPixmap glXCreatePixmap(Display * dpy, GLXFBConfig config, Pixmap pixmap, const int * attrib_list);

PARAMETERS

       dpy
	   Specifies the connection to the X server.

       config
	   Specifies a GLXFBConfig structure with the desired attributes for the window.

       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 window. 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.

       BadMatch is generated if config does not support rendering to windows (e.g., GLX_DRAWABLE_TYPE does not contain GLX_WINDOW_BIT).

       BadWindow is generated if pixmap is not a valid window XID.  BadAlloc is generated if there is already a GLXFBConfig associated with
       pixmap.

       BadAlloc is generated if the X server cannot allocate a new GLX window.

       GLXBadFBConfig is generated if config is not a valid GLXFBConfig.
