Change Endianness (question) #64

Open bucweat opened 6 years ago

bucweat commented 6 years ago

I’m parsing PCAP files...PCAP headers are little endian however Ethernet/IP/TCP and payload in most cases are big endian. Is it possible to switch endianness while parsing a given type in a typeset?

RReverser commented 6 years ago

Yes, absolutely, this is covered in docs as far as I remember.

bucweat commented 6 years ago

Assuming you are talking about the wiki. Endianness is mentioned when defining typeset. Can this be used in a template?

RReverser commented 6 years ago

I don't think it is, but note that typeset config just changes the default endianness; instead, you can pass it on field-by-field basis as type param by using ['uint16', true] for explicit little-endian and false for big-endian.

Ah ha!!!!! That is exactly what I was looking for! Thank you :-)
