fb_font_position()

nserror fb_font_position	(	const struct plot_font_style *	fstyle,
		const char *	string,
		size_t	length,
		int	x,
		size_t *	char_offset,
		int *	actual_x
	)

Find the position in a string where an x coordinate falls.

Parameters

[in]	fstyle	style for this text
[in]	string	UTF-8 string to measure
[in]	length	length of string, in bytes
[in]	x	coordinate to search for
[out]	char_offset	updated to offset in string of actual_x, [0..length]
[out]	actual_x	updated to x coordinate of character closest to x

Returns

NSERROR_OK and char_offset and actual_x updated or appropriate error code on faliure
