mdraw_default_line_break

mdraw_default_line_break(3m17n) 				 The m17n Library				   mdraw_default_line_break(3m17n)

NAME

       mdraw_default_line_break - Calculate a line breaking position.

SYNOPSIS

       int mdraw_default_line_break (MText * mt, int pos, int from, int to, int line, int y)

DESCRIPTION

       Calculate a line breaking position. The function mdraw_default_line_break() calculates a line breaking position based on the line number
       line and the coordinate y, when a line is too long to fit within the width limit.  pos is the position of the character next to the last
       one that fits within the limit.	from is the position of the first character of the line, and to is the position of the last character
       displayed on the line if there were not width limit.  line and y are reset to 0 when a line is broken by a newline character, and
       incremented each time when a long line is broken because of the width limit.

RETURN VALUE

	   This function returns a character position to break the line.
