int t8_dline_extrude_face(const t8_dvertex_t *face, int root_face, t8_dline_t *line)

Given a vertex at the boundary of a line at a root tree boundary, construct the line from it.

Parameters:

face – [in] The face element (vertex).
root_face – [in] The index of the face of the tree.
line – [out] The line that has face as face element at face root_face

Returns:

The face number pf line that coincides with face, thus root_face is returned.
