是一个手机功能的模拟程序

+--------------------------------------------------------------------+

  PURPOSE : This function is used to copy the image of a font into an
            application specific font buffer. The application may modify
            the font. In case of a successful completion the function
            returns DRV_OK. In case the size of the buffer where the
            font image shall be copied to is too small the driver returns
            DRV_INVALID_PARAMS. In case a specific driver implementation
            does not support this functionality the driver returns
            DSPL_FCT_NOTSUPPORTED.
