I cannot compile this initialization of function, why is that?
void n61_init(int (*func)(int cmd, unsigned char c)); |

Is this supposed to be a function that takes a pointer to a function that takes an integer and unsigned char argument, and returns void?
Whatever it is i think i just tried to babble, last i remember, CCS does not allow function pointers. |

The CCS compiler is NOT a full ANSI compliant compiler. Among its non-ANSI portions is its support for pointers to functions. Depending on the version of compiler you have it may or may not support them at all. And the support it does have is somewhat limited. It does however create a pointer to function automatically in switch() statements under the right conditions making state machines very efficient.
