I have this binary file on my linux system .. udit@udit-Dabba ~ $ cat file.enc Salted__s�bO��<0�F���Jw!���]�:`C�LKȆ�l Using hexdump command I see its information like this .. udit@udit-Dabba ~ $ hexdump -C file.enc 00000000 53 61 6c 74 65 64 5f 5f 1b 73 a1 62 4f 15 be f6 |Salted__.s.bO...| 00000010 3c 30 cc 46 ee 10 13 11 84 bf 4a 77 21 a4 84 99 |<0.F......Jw!...| 00000020 0e 5d ef 11 18 3a 60 43 a0 4c 4b 1e c8 86 e6 6c |.]...:`C.LK....l| 00000030 Now I am given a file on some other system whose contents are like this .. 53 61 6c 74 65 64 5f 5f 1b 73 a1 62 4f 15 be f6 3c 30 cc 46 ee 10 13 11

I work a lot with network and serial communications software, so it is often necessary for me to have code to display or log hex dumps of data packets. Every time I do this, I write yet another hex-dump routine from scratch. I'm about to do so again, but figured I'd ask here: Is there any good free hex dump code for C++ out there somewhere? Features I'd like: N bytes per line (where N is somehow configurable) optional ASCII/UTF8 dump alongside the hex configurable indentation, per-line prefixes, per-line suffixes, etc. minimal dependencies (ideally, I'd like the code to all be in a header file

.... finalize(char *hdrs, sendip_data *headers[], int index, sendip_data *data, sendip_data *pack) { ........ For debugging purposes I want a hex dump of the data and pack structures, which are of type sendip_data , a really complex structure. Actually they contain some binary information so I am not sure whether output of my project is correct or not. So for debugging purposes, I want to write the data into a file so that I can use hexdump as follows - $hexdump -C file.txt Also as this is a run time generation of a n/w packet so I am also not sure about the length of data and pack structure
