"struct _ntl_gbigint_body" 在哪里定义的？

Question

我正在浏览 NTL 代码，但找不到 struct _ntl_gbigint_body 定义：

$ grep -r _ntl_gbigint_body *
include/NTL/ZZ.h:WrappedPtr<_ntl_gbigint_body, Deleter> rep;
include/NTL/lip.h:struct _ntl_gbigint_body;
include/NTL/lip.h:typedef _ntl_gbigint_body *_ntl_gbigint;
Binary file src/RR.o matches
.....
Binary file src/GF2E.o matches
src/lip.cpp:typedef WrappedPtr<_ntl_gbigint_body, _ntl_gbigint_deleter> _ntl_gbigint_wrapped;
Binary file src/mat_ZZ_p.o matches
......

我只是好奇它是在哪里定义的。

Answer 1

与NTL的作者Victor Shoup讨论后，他给出了答案：

It's actually never declared.
A pointer to it is like a void pointer, but with better error checking.
