If link is DI_LINK_NIL, a handle is returned to the first link whose endpoint specified by endpoint matches the lnode specified by lnode. RETURN VALUES
Upon successful completion, a handle to the next link is returned. Otherwise, DI_LINK_NIL is returned and errno is set to indicate the error. ERRORS
