getInt8(char& variable);

== Description

If required, throw a `TestInStreamException` (see `throwExceptionIfInputLimitExhausted`); otherwise, consume the 8‐bit unsigned integer type code, verify the type of the next value in this stream, consume that 8‐bit signed integer value into the specified `variable` if its type is appropriate, update the cursor location, and return a reference to this stream. If the type is incorrect, then this stream is marked invalid and the value of `variable` is unchanged. If this stream is initially invalid, this operation has no effect. If this function otherwise fails to extract a valid value, this stream is marked invalid and the value of `variable` is undefined.
