Decodes a varint from the bytes in buf, storing it into *n. Returns the number of bytes read, or 0 if the data is invalid (buffer too short or num

Copies my contents to memory starting at `dst`, using `memcpy`.

Converts a Retained into a raw pointer with a +1 reference that must be released. Used in C++ functions that bridge to C and return C references.

Unsigned version:

Reads the next character from the input. Fails if input is at EOF.

Exactly like memcmp, but safely handles the case where dst or src is NULL and size is 0 (as a no-op), instead of producing "undefined behavior" as
