How swap big to host int8 number?

I work with binary protocol, so it's normally to use:

int32_t number = SOME_NUMBER;
CFSwapInt32BigToHost(number);

But what's about int8_t?

Endianess usually refers to the order of bytes. Since every byte has its own address, a multi-byte word can be ordered in two (or more, but typically it has big-endianness or little-endiness) different directions, higher byte higher address or lower byte higher address. So you need a byte swap.

Bits are not addressable. So there is no need to deal with endianness. And even if there is a operation that indexes a bit, nobody would be that crazy to make the bit 0 the most significant. So you do not need a bit swap.
