- * Interface for Supporting DGA to Framebuffers under Java
- * -------------------------------------------------------
- *
- * This interface will allow third party (and Sun) framebuffers which
- * support the Direct Graphics Access (DGA) interface to be accessed with
- * DGA in Java applications.
- *
- * It coexists with the existing device-independent interfaces provided in
- * libsunwjdga.so.
- *
- * Framebuffers desiring access to Java DGA must supply a dynamically
- * loaded library named "libjdga<fbname>.so", where <fbname> is the name
- * returned by the VIS_GETIDENTIFIER ioctl as defined in the Solaris
- * VISUAL environment (visual_io(7i)). For example, the Java DGA library
- * for Sun's cg6 framebuffer will be named libjdgaSUNWcg6.so.
- *
- * Because multiple instances of a framebuffer type may exist on a system,
- * the device-dependent library must avoid the use of static or global
- * variables for any framebuffer-related variables. In other words it
- * must be reentrant.
- *
- * The device-independent function Solaris_JDga_LibInit() is called in the
- * static initializer for X11Graphics.java. Solaris_JDga_LibInit() will be
- * modified to seek out a device-dependent DGA library as follows.
- *
- * - DGA grab the DefaultRootWindow to get a Dga_drawable.
- *
- * - Use the Dga_drawable ID to get the device file descriptor
- * fd = dga_win_devfd(dga_draw_id)
- *
- * - Use the VIS_GETIDENTIFIER ioctl to get the device name string.
- *
- * - Construct the library path name using the device name string.
- * The device-dependent library must be located in a location specified
- * in the LD_LIBRARY_PATH.
- *
- * - The device-dependent library will be dlopen'ed and then a dlsym will
- * be performed for the function "SolarisJDgaDevOpen", which must
- * be implemented by the device-dependent library writer.
- *
- * - The function SolarisJDgaDevOpen() will then be called with a
- * pointer to a SolarisJDgaDevInfo structure. This structure will
- * have its major and minor version numbers filled in with their
- * current values by the device-independent calling code. The
- * device-dependent library must examine these version numbers and
- * act as follows:
- *
- * - In all cases, the device-dependent code should reset the
- * supplied major and minor version numbers to those of the
- * device-dependent library.
- *
- * - If the supplied major version number is not the same as that
- * of the device library, the open must fail and return JDGA_FAILED.
- *
- * - If the supplied minor version number is less than or equal to
- * the device minor version number, then backward compatibility
- * is assumed and the open should return JDGA_SUCCESS.
- *
- * - If the supplied minor version number is greater than the
- * device minor version number, the open should also return
- * JDGA_SUCCESS. The returned device minor version number will
- * indicate to the device-independent code what features are
- * supported in the device library.
- *
- * - The function SolarisJDgaDevOpen() must also return a structure
- * containing function pointers as given in the SolarisJDgaDevFunc
- * structure below. The winlock and winunlock functions are
- * required only if there is some device-specific locking to be done
- * in addition to the DGA lock. If this is not required for the device
- * these function pointers may be specified as NULL pointers.
