Hi I got this example from https://learn.microsoft.com/en-us/cpp/c-runtime-library/reference/set-se-translator?view=msvc-170
// crt_set_se_translator_clr.cpp// compile with: cl /W4 /clr crt_set_se_translator_clr.cpp#include <windows.h>#include <eh.h>#include <stdio.h>#include <exception>int thrower_func( int i ) { int y = 0; int *p = &y; *p = i / *p; return 0;}class SE_Exception : public std::exception{private: const unsigned int nSE;public: SE_Exception() noexcept : SE_Exception{ 0 } {} SE_Exception( unsigned int n ) noexcept : nSE{ n } {} unsigned int getSeNumber() const noexcept { return nSE; }};class Scoped_SE_Translator{private: const _se_translator_function old_SE_translator;public: Scoped_SE_Translator( _se_translator_function new_SE_translator ) noexcept : old_SE_translator{ _set_se_translator( new_SE_translator ) } {} ~Scoped_SE_Translator() noexcept { _set_se_translator( old_SE_translator ); }};#pragma unmanagedvoid my_trans_func( unsigned int u, PEXCEPTION_POINTERS ){ throw SE_Exception( u );}void DoTest(){ try { thrower_func( 10 ); } catch( const SE_Exception& e ) { printf( "Caught SE_Exception, error %8.8x\n", e.getSeNumber() ); } catch(...) { printf( "Caught unexpected SEH exception.\n" ); }}#pragma managedint main() { Scoped_SE_Translator scoped_se_translator{ my_trans_func }; DoTest();}I tried to compile with mingw-w64 on my Windows 10 x64 pro laptop (msys2 installation).
