Function	Description
`_sio_byte_at`
`_sio_copy`
`sio_new`	Create empty StringIO with given capacity.
`sio_from`	Create StringIO from existing string.
`sio_write`	Write data at current position. Returns bytes written.
`sio_read`	Read n bytes from current position. Returns bytes read.

`sio_rewind`	Reset position to beginning.
`sio_eof`	1 if at end of data.
`sio_len`	Current data length.
`sio_pos`	Current read/write position.
`sio_string`	Copy all contents to out buffer. Returns length.
`sio_putc`	Write a single byte at current position.
`sio_getc`	Read a single byte at current position. Returns -1 at EOF.
