/GX (Enable Exception Handling)

Enables synchronous exception handling with the assumption that extern C functions never throw an exception.

/GX

It is equivalent to /EH (Exception Handling Model).

/GX is in effect, by default, when you compile from within the development environment. By default, /GX- is enabled when using command-line tools.

For more information, see C++ Exception Handling.

/GX is deprecated; use /EH (Exception Handling Model) instead. For more information, see Deprecated Compiler Options.
