You are right. Gtags-cscope(1) does not perfectly reproduce cscope(1). Since Global doesn't recognize the function which is calling, the function field is meaningless when referenced. Do you think this should be changed to "unknown" to avoid misunderstandings? $ man global >>BUG >> The function field of the display is almost <unknown> since Global >> doesn't recognize it. >> >> ´Find functions called by this function´ is not implemented.
