Segmentation Fault Using cURL

Segmentation Fault Using cURL

I think the issue was by ths following , I'm not familiar with cURL, but two things that might help you, so forgive me if I speak nonsense:
char *url = "http://pixhost.tk/test.txt"; is a read-only string, so change it to const char *url = "http://pixhost.tk/test.txt"; this might reveal your problem during compilation. You don't check for the result of fopen, maybe it failed, which explains the segfault, and it is seems likely to me since you try to open "/Users/Nathan/Desktop" which should be a directory AFAIK.

will help you So after some thought the issue I believe is that your buffer is being written to as you're reading it. In some cases the buffer is not done being written to and you remove some of the data from it (which could mean that you may read an empty buffer because the write isn't done). This is because you are using popen and simply piping data from another process. What I would recommend is that for one you use the C++ standard for getline (although both are somewhat unsafe) and that you have some leeway for reading data from the pipe. Retry logic might be what you need as I can't think of a clean way to solve this. If anyone knows please post it, I'm posting this because this is what I believe to be the likely culprit of the problem.
Also if you're coding in C++ I highly recommend that you use the C++ libraries so that you're not constantly mixing or casting between types (such as string to char * and such, it just saves you some hassle) and that you use the safer versions of methods so you avoid errors such as buffer overflows.

Any of those help You are passing the value of an environment variable $gjdvc1A as an argument. And your program does not have any argument checking, it will always crash when the value for the environment variable is not set

help you fix your problem Please use sscanf() instead. Try to avoid strtok() at all costs unless otherwise absolutely neccessary.
