FUNCTION

NAME
        write_bytes - Write characters at a given position in a file.


SYNTAX
	int write_bytes(string filename, int position, string text)

DESCRIPTION
	Write the string 'text' at a given position in a file. If the position
	is negative it is counted backwards from the end of the file.
	If the position is outside the file the nothing is written.
	If the 'text' extends outside the file then the file is extended.


RETURN VALUES
	1 - Succesfully wrote to file.
	0 - Failed to write to file.


NOTE
	Observe that you overwrite existing data in the file. Not like
	write_file where you only append data at the end.
