[erlang-questions] Decoding integers serialised by Erlang

The ei library has functions for decoding Erlang terms in binary format. One of
these functions is ei_get_type(const char *buf, const int *index, int *type, int *size).
The returned value for "type" may be ERL_SMALL_INTEGER_EXT, which indicates that
the data is an 8-bit item.

My question: Do the 8 bits represent an integer 0..255? Or -128..127? And, is the
representation always the same, or does it depend on the platform that the encoding
took place on?
