Python SWIG中结构数组的处理

我试图包装一个C函数，它需要向它传递一个结构数组

.i文件中的函数定义为：

extern HRESULT WINAPI ScriptItemize(
const WCHAR           *pwcInChars,    // In   Unicode string to be itemized
int                   cInChars,       // In   Codepoint count to itemize
int                   cMaxItems,      // In   Max length of itemization array
const SCRIPT_CONTROL  *psControl,     // In   Analysis control (optional)
const SCRIPT_STATE    *psState,       // In   Initial bidi algorithm state (optional)
SCRIPT_ITEM           *pItems,        // Out  Array to receive itemization
int                   *pcItems);      // Out  Count of items processed (optional)

structs SCRIPT_控件、SCRIPT_状态和SCRIPT_项之前都已在.i文件中定义

我可以通过包括以下行来指示pcItems是返回值：

%include <typemaps.i>
%apply int *OUTPUT {int *pcItems};

我得到这个警告：

Can't apply (SCRIPT_ITEM *OUTPUT). No typemaps are defined.

我如何指出pItems是一个返回值

另外，如何从Python中创建脚本项结构数组？

我已经找到了通过更改.I文件来实现这一点的方法，如下所示：

%include <carrays.i>

%array_class(SCRIPT_ITEM, SCRIPT_ITEM_ARRAY);

extern HRESULT WINAPI ScriptItemize(
const WCHAR           *pwcInChars,    // In   Unicode string to be itemized
int                   cInChars,       // In   Codepoint count to itemize
int                   cMaxItems,      // In   Max length of itemization array
const SCRIPT_CONTROL  *psControl,     // In   Analysis control (optional)
const SCRIPT_STATE    *psState,       // In   Initial bidi algorithm state (optional)
SCRIPT_ITEM_ARRAY     *pItems,        // Out  Array to receive itemization
int                   *pcItems);      // Out  Count of items processed (optional)

%include
%数组类（脚本项、脚本项、数组）；
外部HRESULT WINAPI脚本项目化(
常量WCHAR*pwcInChars，//以要逐项列出的Unicode字符串表示
int cInChars，//在要逐项列出的代码点计数中
int cMaxItems，//在项目化数组的最大长度中
const SCRIPT_CONTROL*psControl，//在分析控件中（可选）
const SCRIPT_STATE*psState，//处于初始bidi算法状态（可选）
SCRIPT_ITEM_ARRAY*pItems，//输出数组以接收项目化
int*pcItems）；//已处理项目的超出计数（可选）

%include <carrays.i>

%array_class(SCRIPT_ITEM, SCRIPT_ITEM_ARRAY);

extern HRESULT WINAPI ScriptItemize(
const WCHAR           *pwcInChars,    // In   Unicode string to be itemized
int                   cInChars,       // In   Codepoint count to itemize
int                   cMaxItems,      // In   Max length of itemization array
const SCRIPT_CONTROL  *psControl,     // In   Analysis control (optional)
const SCRIPT_STATE    *psState,       // In   Initial bidi algorithm state (optional)
SCRIPT_ITEM_ARRAY     *pItems,        // Out  Array to receive itemization
int                   *pcItems);      // Out  Count of items processed (optional)
