how to save a function pointer?

[Eric]

        my patch replace the system keyboard, I use sysgettrapaddress to
get the system keyboard function pointer first, I want to save it in
database so that I can recover it later. 

void (*oldKeyboardPtr)(KeyboardType);
oldKeyboardPtr=SysGetTrapAddress(0xA2E2);

how to save the oldKeyboardPtr?
