Function gmsh_sys::gmshModelGeoAddCurveLoop

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

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.
