@@ -6,12 +6,24 @@ This example demonstrates usage of C++ exceptions in ESP-IDF.
By default, C++ exceptions support is disabled in ESP-IDF. It can be enabled using `CONFIG_COMPILER_CXX_EXCEPTIONS` configuration option.
In this example, `sdkconfig.defaults` file sets `CONFIG_COMPILER_CXX_EXCEPTIONS` option. This enables both compile time support (`-fexceptions` compiler flag) and run-time support for C++ exception handling.
In this example, the `sdkconfig.defaults` file sets the `CONFIG_COMPILER_CXX_EXCEPTIONS` option. This enables both compile time support (`-fexceptions` compiler flag) and run-time support for C++ exception handling.
Example source code declares a class which can throw exception from the constructor, depending on the argument. It illustrates that exceptions can be thrown and caught using standard C++ facilities.
The example source code declares a class which can throw exception from the constructor if the argument provided is equal to `0`. This is used to demonstrate that exceptions can be thrown and caught using standard C++ facilities.
**Note: Due to the use of the C++ exceptions, this example is written in C++ instead of C.**
## How to use example
### Hardware Required
This example should be able to run on any commonly available ESP32 development board.
