Re: Represent byte array longer than MAX_BYTE_STR_LEN as hexstring

Really in my case the largest had been 64 bytes. I have rewritten things to use tvb_memdup, tvb_memcp, and tvb_memeql. At this point it's a bit academic, but is the use of tvb_get_ptr() so bad in this case. It is used quite frequently in dissector code and other libwireshark base code. Really just trying to understand now. On Sat, Aug 3, 2019 at 9:32 PM Guy Harris <guy () alum mit edu> wrote:

I do not need the actual bytes from the tvb after I render it as a hexstring.Render where?In the packet detail.OK, so we could increase MAX_BYTE_STR_LEN to, say, 256, but: 1) that wouldn't handle an *arbitrary* length - it'll *still* get cut off at 240 bytes; 2) it'd be a lot of hex digits to stare at, possibly requiring horizontal scrolling. How big can this field get? ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org ?subject=unsubscribe
