// P/Invoke wrapper for pkgread.dll (x86).

//
|
||
// 说明：此文件兼容 .NET Framework 4。
|
||
// - 将项目 Platform target 设置为 x86（因为你只编译了 x86 的本机 DLL）。
|
||
// - pkgread.dll 返回了很多需由调用者释放的 LPWSTR 指针；header 中未提供通用释放函数，示例中调用 CRT 的 free（msvcrt.dll）来释放。
|
||
// 如果能修改 pkgread.dll 并导出专用释放函数（如 PackageReadFreeString），那是更安全的做法。
