1  //If big-little endian problem: switch tmp1&0xFF00 + tmp2&0x00FF ->  /*****************************************************************
2  // tmp1&0x00FF + tmp2&0xFF00  Function to read AC physics data v1.1
3    Author: Petter Hofverberg, petter@particle.kth.se
4    
5    0408 v1.0 alive
6    0409 Added shifting operators to fix problem with odd data (BBAC|11DD)
7                                                                  -----
8    Errors: (returned to the main program as the variable "err")
9    err=
10    0 - Ok
11    1 - Data found, but corrupt
12    2 - Data dont found in buffer
13    
14    ToDo: i)  do it endian-independent
15          ii) check for more events in the same file?
