What are the best ways to search a binary file for a specific sequence of hex values? The sequence that I'm looking for is: FF D8 FF E0 00 10 4A 46 49 46 00. The files that I'm searching are 14K bytes in size. I suppose the easiest way would be slurp the whole file in at once and then search for my sequence in some string variable. But what if my files were huge? Do I read in one character at a time until I find an FF and then I look for the D8 and then the rest of the hex values resetting my search if I fail to find the next value in the sequence? Or do I read in 1K of data at a time and search that for my sequence? Could some of you who have been down this road before point me in the right direction? I'm not asking you to write my code for me (unless you want to). I'm just looking for pointers and suggestions.
