Where can I ask questions of highly skilled and experienced C programmers?

I'm intermediate level C programmer trying to sharpen my skill and level up.

Sometimes I could use some expert guidance, usually in something specific to C programming.

Sometimes it's low level semantics of bits, types, casts.

Examples are:

"How do I cleanly manage error detection, processing, and recovery in this scenario?"

"I want to write code that verifies all malloc()'ed memory is correctly free()'d, is xyz a good idea?"

"I have to represent fifteen items which are mostly the same but also all different, how do I structure this program to avoid code duplication and isolate/interface the specific and general code?"

"I wrote this awesome hack... Wait... How does it smell?"

"I feel compelled to reinvent this wheel and polish it! Is there a better way?"

"Should I call this szFooBar myapiFooBar APIFoobar api_FooBar api_foo_bar, or fb?"

Stuff like that.

Thank you for advice.
