Another project, another bump in the road and another chance to learn. I've been trying to open gzipped files and parse data from them and hit a snag. I have data in gzips with a place followed by an ip or ip range sort of like this:
I was able to modify some code I found that works fine for parsing the data to only show the ips:
Result:
However, when I add it to the code I have for opening the gzips and reading them I get a segmentation fault. Here is the code I am trying to work from now:
