Perhaps show some effort by listing a few cases yourself first.

static functions have a visibility restricted to the translation unit in which they're declared. You can use them anywhere a regular function can be used, but you should use them everywhere you can because they follow the rule of minimal scope.

If you have a small program with just one *.c file, then static functions aren't all that useful. The advantage of statics is with larger programs whose projects consist of several *.c files. In this case, as Narue already said, make all the functions static that do not need global scope to other *.c files. And the same with global data objects, make them static too if they don't need to be referenced in more than one *.c file.
