function pointer does not call a function in CW 5.0

Hi,

Under CW 5.0, I have declared a simple function pointer:

void (*fp) ();

the call:

fp = &MCU_init; // just an example

In simulation, fp = the address of MCU_init, but does not execute the function.

I am using the small memory model. I also used a typedef, but still no luck.

Is it a compiler setting?

Hello

How are you calling the function?

fp = &MCU_init; will only initialize fp with the address of function MCU_init.

To call the function you have to write

fp();

Thanks

Forgot about the call.

Besides using function pointers in a table, what other practical uses are there?
