swap_bank.h

Go to the documentation of this file.

// This contains code for byte swapping EVIO banks. The code
// is mostly copied from HDEVIO, but modified to just print
// any errors rather than use the error flag/message system
// built into HDEVIO. It can therefore be used outside of
// HDEVIO.
