// MIOFILE lets you do formatted I/O to either a FILE or a memory buffer,
// depending on how you initialize it.
//
// output:
//  init_file(): output goes to the FILE* that you specify
//  init_mfile(): output goes to an MFILE (i.e. a memory buffer);
//     you can call MFILE::get_buf() to get the results
// input:
//  init_file(): input comes from the FILE* that you specify
//  init_buf(): input comes from the buffer you specify.
//   This string is not modified.
//
// Why is this here?  Because on Windows (9x, maybe all)
// you can't do fdopen() on a socket.
