cairo_stroke.RdA drawing operator that strokes the current path according to the current line width, line join, line cap, and dash settings. After cairo_stroke(), the current path will be cleared from the cairo context. See cairo_set_line_width(), cairo_set_line_join(), cairo_set_line_cap(), cairo_set_dash(), and cairo_stroke_preserve().

Note: Degenerate segments and sub-paths are treated specially and provide a useful result. These can result in two different situations:
1. Zero-length "on" segments set in cairo_set_dash(). If the cap style is %CAIRO_LINE_CAP_ROUND or %CAIRO_LINE_CAP_SQUARE then these segments will be drawn as circular dots or squares respectively. In the case of %CAIRO_LINE_CAP_SQUARE, the orientation of the squares is determined by the direction of the underlying path.
2. A sub-path created by cairo_move_to() followed by either a cairo_close_path() or one or more calls to cairo_line_to() to the same coordinate as the cairo_move_to(). If the cap style is %CAIRO_LINE_CAP_ROUND then these sub-paths will be drawn as circular dots. Note that in the case of %CAIRO_LINE_CAP_SQUARE a degenerate sub-path will not be drawn at all, (since the correct orientation is indeterminate).
In no case will a cap style of %CAIRO_LINE_CAP_BUTT cause anything to be drawn in the case of either degenerate segments or sub-paths.
