Function gmsh_sys::gmshModelGeoAddSurfaceLoop

pub unsafe extern "C" fn gmshModelGeoAddSurfaceLoop(
    surfaceTags: *mut c_int, 
    surfaceTags_n: usize, 
    tag: c_int, 
    ierr: *mut c_int
) -> c_int

Add a surface loop (a closed shell) formed by surfaceTags. If tag is positive, set the tag explicitly; otherwise a new tag is selected automatically. Return the tag of the shell.
