Hi Gabriel,
Thank you very much for your review. This is a list of important changes I made
since the last version:
* global variables are now static
* trace and sdt are printed in a table format
* added a verbose option for trace formatting (this prints SCSI opcode and other
verbose information)
* created small macro for endianness conversion
* removed linked list structures. now reading information directly through mmap
* rewrote main() so that it handles usage flags correctly
* error messages now use errno and strerror()
I would appreciate it if you could take another look at this version of the
code, when you have some time to spare.
Thanks.
