Retarget fprintf

[nlemoz]

Hi.

I am trying to retarget fprintf on kinetis sdk 1.3 using gcc.

I am doing this so I can send output to multiple UARTs depending on the "FILE" I print to.

I can retarget printf successfully by implementing a _write function, but this does not work for fprintf.

Can someone give me a hint on how to retarget fprintf for gcc?

Thanks,

Nick
