get_chars

Retrieves a sequence of characters.

The characters that are retrieved are those characters at positions from start_pos up to, but not including end_pos. If end_pos is negative, then the characters retrieved are those characters from start_pos to the end of the text.

Note that positions are specified in characters, not bytes.

Parameters:

this	a Editable
start_pos	start of text
end_pos	end of text

Returns:

a pointer to the contents of the widget as a string. This string is allocated by the Editable implementation and should be freed by the caller.
