Searching a log file [duplicate]

Answer 1

You could use a circular buffer.

1. Open the file
2. Read a line
3. Read address and discart it
4. Read first value and put it into the buffer
5. Read next value, and throw last value of the buffer (std::list could be good for that)
6. Check if buffer contains the pattern
7. Loop through 5 up to the end of the line
8. Loop through 2 up to the end of the file

Answer 2

Python, just read in line, split, chuck the first part, concat the hex into a string, and search. Something like this would work:

hex = ""
for each line in lines:
    tmp = line.split() // split on whitespace
    hex += tmp[1:] // grab everything after address

if hex.contains(pattern):
    # do something

Or use a regex, but you get the basic idea.
