program creates a file, but won't write to it - c

Question

I'm very novice at C but I'm trying to learn. I'm trying right now to make a program read from a csv file and take only it's integers from it, and write those out to a seperate .txt file. I'm not seeing why it will create a file, but why it won't write anything to it. Here's the code. in the methods 'getTokensFromLineforOutput' and 'writeOutput' is where I try to do my writing, everything else works fine, and if you were to take away those two methods and run it as just a program reading from a csv file it operates as intended. But writing is where I'm running into. IDK if i'm able to attach a document so for reference here's the csv file I made from notepad:
3,1, joe
45,0, sandy
5,1, mary
12,0, eugene
11,0, alex

Answer 1

(If I could comment this I would)
Try putting parentheses around your de referencing * and variable..
(ch = (*inThLine))
