/** \brief Attach a specific caca graphical context to a caca canvas.
*
* Create a graphical context using device-dependent features (ncurses for
* terminals, an X11 window, a DOS command window...) that attaches to a
* libcaca canvas. Everything that gets drawn in the libcaca canvas can
* then be displayed by the libcaca driver.
*
* If no caca canvas is provided, a new one is created. Its handle can be
* retrieved using caca_get_canvas() and it is automatically destroyed when
* caca_free_display() is called.
*
* If no driver name is provided, \e libcaca will try to autodetect the best
* output driver it can.
*
* See also caca_create_display().
*
* If an error occurs, NULL is returned and \b errno is set accordingly:
* - \c ENOMEM Not enough memory.
* - \c ENODEV Graphical device could not be initialised.
*
* \param cv The caca canvas or NULL to create a canvas automatically.
* \param driver A string describing the desired output driver or NULL to
* choose the best driver automatically.
* \return The caca graphical context or NULL if an error occurred.
