How can I intercept a win api calling?

Hi All,

I need intercept a win api calling, sush as GetLocalTime, and post my own value.
Anybody can help me?

I don't know if that is possible...there might be a way to modify KERNEL32.DLL, USER.EXE, or GDI.EXE or whatever file contains the function, but that doesn't seem safe...

Or actually you might be able to revector the interrupt, whatever interrupt Windows uses, and then if it is a specific function, your own code could do stuff, otherwise the default code could be executed.

Maybe.

I think you should write a API hook?
