#define JSON_NOEXCEPTION
Exceptions can be switched off by defining the symbol JSON_NOEXCEPTION
. When defining JSON_NOEXCEPTION
, #!cpp try
is replaced by #!cpp if (true)
, #!cpp catch
is replaced by #!cpp if (false)
, and #!cpp throw
is replaced by #!cpp std::abort()
.
The same effect is achieved by setting the compiler flag -fno-exceptions
.
By default, the macro is not defined.
#undef JSON_NOEXCEPTION
The explanatory what()
string of exceptions is not available for MSVC if exceptions are disabled, see #2824.
??? example
The code below switches off exceptions in the library. ```cpp #define JSON_NOEXCEPTION 1 #include <nlohmann/json.hpp> ... ```
