Hi How can I convert this C++ code to Kotlin native ``` include lt iostream gt include lt windows h gt include lt Commdlg h gt Gobal Variables and declarations OPENFILENAME ofn a another memory buffer to contain the file name char szFile 100 int main ZeroMemory amp ofn sizeof ofn ofn lStructSize = sizeof ofn ofn hwndOwner = NULL ofn lpstrFile = szFile ofn lpstrFile 0 = 0 ofn nMaxFile = sizeof szFile ofn lpstrFilter = All 0 0Text 0 TXT 0 ofn nFilterIndex =1 ofn lpstrFileTitle = NULL ofn nMaxFileTitle = 0 ofn lpstrInitialDir=NULL ofn Flags = OFN PATHMUSTEXIST|OFN FILEMUSTEXIST GetOpenFileName amp ofn Now simpley display the file name MessageBox NULL ofn lpstrFile File Name MB OK return 0 ``` Currently Im strugling with creating OPENFILENAME object It is alias of tagOFNA and it takes `rawPtr kotlinx cinterop NativePtr` in its constructor How do I create `NativePtr`

okay I figured out how to create OPENFILENAME Here is my progress ```fun main args Array lt String gt memScoped val result = alloc lt tagOFNA gt SecureZeroMemory invoke result ptr sizeOf lt tagOFNA gt toULong val szFile = ByteArray 100 alloc lt CHARVar gt result apply hwndOwner = null lpstrFile = szFile GetOpenFileNameA result ptr ``` Now I need help with creating ` char szFile 100 ` and its pointer for `ofn lpstrFile`

A bit more progress ```fun main args Array lt String gt memScoped val result = alloc lt tagOFNA gt SecureZeroMemory invoke result ptr sizeOf lt tagOFNA gt toULong val szFile = ByteArray 100 szFile 0 = 0 val pinnedSzFile = szFile pin val filter = All 0 0Text 0 TXT 0 encodeToByteArray pin result apply hwndOwner = null lpstrFile = pinnedSzFile addressOf 0 nMaxFile = pinnedSzFile ofn lpstrFilter = All 0 0Text 0 TXT 0 lpstrFilter = filter addressOf 0 nFilterIndex = 1u lpstrFileTitle = null nMaxFileTitle = 0u lpstrInitialDir = null Flags = OFN PATHMUSTEXIST or OFN FILEMUSTEXIST toUInt GetOpenFileNameA result ptr ``` Need help with ` val filter = All 0 0Text 0 TXT 0 encodeToByteArray pin ` it says `illegal escape 0`
