* @return:
* The number of bytes effectively read by the stream.
*
* @note:
* This function performs a seek *or* a read operation depending on the
* argument values. If `count` is zero, the operation is a seek to
* `offset` bytes. If `count` is >~0, the operation is a read of `count`
* bytes from the current position in the stream, and the `offset` value
* should be ignored.
*
* For seek operations, a non-zero return value indicates an error.
* If count >~0, return the number of bytes effectively read by the
* stream (after seeking to `offset`). If count ==~0, return the status
* of the seek operation (non-zero indicates an error).
