- /* `pic_init' and `pic_free' to allow you to manually allocate and */

- /* initialize any additional global data, like a module specific */

- /* interface, and put them in the global pic container defined in */

- /* `ftpic.h'. If you don't need them just implement the functions as */

- /* empty to resolve the link error. Also the `pic_init' and */

- /* `pic_free' functions should be declared in `pic.h', to be referred */

- /* by driver definition calling `FT_DEFINE_DRIVER' in following. */

- /* */

- /* When FT_CONFIG_OPTION_PIC is not defined the struct will be */

- /* allocated in the global scope (or the scope where the macro is */

- /* used). */
