Weź to jak człowiek trzymaj w unique_ptr z własnym deleterem,
to unikniesz wycieków (jeśli jakieś są, bo nie zauważyłem
w tym kodzie).
auto closefile = [](FILE* f){fclose(f);};
std::unique_ptr<FILE, decltype(closefile)> infile{fopen("path", "r"), closefile};
Wtedy przestajesz się martwić, czy i kiedy wołać fclose,
bo to zrobi za Ciebie destruktor unique_ptr.
