Function rgmsh::interface::geo::add_curve_loop

pub unsafe extern "C" fn add_curve_loop(
    curveTags: *mut i32, 
    curveTags_n: usize, 
    tag: i32, 
    ierr: *mut i32
) -> i32

Add a curve loop (a closed wire) formed by the curves curveTags. curveTags should contain (signed) tags of model enties of dimension 1 forming a closed loop: a negative tag signifies that the underlying curve is considered with reversed orientation. If tag is positive, set the tag explicitly; otherwise a new tag is selected automatically. Return the tag of the curve loop.
