Finally I have a valid reason to learn about memory management. It was also hella weird when encountering it.
minus-squareLedgeDrop@lemmy.ziplinkfedilinkarrow-up17·3 days agoWithout getting too critical of your code (congrats BTW), never use strcpy instead use strlcpy. strcpy will happily allow you to create buffer overflows (a common challenge with C) which will cause your application to crash. You’ll find more details here. Good luck!
