line_set_segments Function

public function line_set_segments(line, segments) result(status)

Draw a line's points as separate segments (pairs of points: 1-2, 3-4, ...) instead of a strip. Set before its points are drawn. Returns 0, or -1 on failure.

Arguments

Type IntentOptional Attributes Name
type(c_ptr), intent(in) :: line

line handle
logical, intent(in) :: segments

true for separate segments, false for a strip

Return Value integer(kind=c_int)
