Hello ahamed,

Just great! It works very nice. I've been adding some functions to print
in decimal copying the logic from your print_bytes function.

After trying and trying and investigating I've learned some about C and I've been able to modify the code succesfully. I'm still pending with some other sequence
to extract, but I'm studying deeply your code ad I hope to be able to replicate how you do if I get issues I hope you can give a hand one more time.

Hello wisecracker,

Thanks for your help and time. I have installed python 3.3.2 and I have the files in same folder in windows, I'm not sure why I don't receive the same output. I'll keep trying because I'm interested to learn.

Thanks again

Regards

Hello again ahamed,

One question:

The script works fine with small files, but I tested with a binary of 20MB and I received the error:

Code:

$ ./extract5 input > output
Segmentation fault (`core' generated)

And the file "extract5.exe.stackdump" was created containing this:

Code:

Exception: STATUS_ACCESS_VIOLATION at eip=004012CA
eax=00790001 ebx=0000003F ecx=80000038 edx=005B0102 esi=0000002E edi=00000061

End of stack trace

What did this happen? Is possible to fixed in order to process a file as bigger than 2GB?

Thanks in advance.
