There is missing NULL check, but it doesn't crash, because the function would get nonexistent filename only if filesystem driver would do something strange (or file would be deleted just between readdir and fopen). xD I also noticed, that I don't close files and directories. Not a big deal, because fully functional and 100% correct program wasn't the goal here. :)

EDIT: Actually fopen would return NULL when file is not readable. My bad. Anyway, such problems are trivial to debug.

I like that I don't have to spend the time debugging trivial problems like these in Rust though. The compiler catches them for me, and I get more time and brain power to spend debugging nontrivial problems. It adds up.

Everything is matter of price. Such an error is nobrainer actually, because just before I get an error message. If I don't know that yet, I run on gdb and everything's clear. Couple of seconds. How manyof them I have to do to ballance learning a new language(and I'm not sure if I like it eventually)? If I was a system software developer, that would probably be a good choice. I program mostly in high level languages, so maybe not. :)

Wasn't it? It reminds me about the old article by Strostrup on c/c++ for beginners (I seem to link to this quite often, apologies if it gets repetitive):

One point of using c++ over c is that it should be easier to get a program that is in fact correct - regarding things like closing files etc. (that said conciously leaking some recources ("do and die") could be considered idiomatic c i suppose).

Yes, I consider that memory management is the biggest problem with C. Always the question is what is more valueable to you: simplicity or memory management.
