# Character I/O

Built-ins to input and output characters or byte strings

## Predicates

> get(-Code)
>   Reads the next character or byte from the current input stream
> get(+Stream, -Code)
>   Reads the next character from the input stream Stream
> get_char(-Char)
>   Reads the next character from the current input
> get_char(+Stream, -Char)
>   Reads the next character from the input stream Stream
> nl
>   A newline is printed on the output stream.
> nl(+Stream)
>   A newline is printed on the output stream Stream.
> put(+Code)
>   The character represented by the integer Code is put onto the buffered current output
> put(+Stream, +Code)
>   The character represented by the integer code Code is put onto the buffered output stream Stream.
> put_char(+Char)
>   Puts the single character text Char onto the buffered current output.
> put_char(+Stream, +Char)
>   Puts the single character text Char onto the buffered output stream Stream.
> read_string(+Stream, ?Length, -String)
>   Reads a string from Stream up to a specified length
> read_string(+Stream, +Delimiters, ?Length, -String)
>   Reads a string from the stream Stream up to a delimiter or up to a specified length.
> read_string(+Stream, +SepChars, +PadChars, -Separator, -String)
>   Reads a string from the stream Stream up to a delimiter.
> read_token(-Token, -Class)
>   Succeeds if the next token from the current input stream is successfully read and unified with Token and its token class with Class.
> read_token(+Stream, -Token, -Class)
>   Succeeds if the next token from the input stream Stream is successfully read and unified with Token and its token class with Class.
> tyi(-Code)
>   Succeeds if the code of the next character read in raw mode from the current input is successfully unified with Code.
> tyi(+Stream, -Code)
>   Succeeds if the code of the next character read in raw mode from the input stream Stream is successfully unified with Code.
> tyo(+Code)
>   The character represented by the integer Code is put onto the current output in raw mode.
> tyo(+Stream, +Code)
>   The character represented by the integer Code is put onto the output stream Stream in raw mode.
> unget(+Stream)
>   Back up one character on Stream
