Specifies the asynchronous C++ exception handling model.
s
Specifies the synchronous C++ exception handling model.
c

Tells the compiler to always generate runtime termination checks for all noexcept functions. IT forces runtime termination checks in all functions that have a noexcept attribute.
If you specify
c
, you must also specify

or
s
.
Default
OFF
Some exception handling is performed by default.
