This example demonstrates usage of the RTTI feature in ESP-IDF.
By default, RTTI support is disabled in ESP-IDF. It can be enabled using `CONFIG_COMPILER_CXX_RTTI` configuration option.
In this example, `sdkconfig.defaults` file sets `CONFIG_COMPILER_CXX_RTTI` option. This enables compile time support for RTTI (`-frtti` compiler flag).
The example prints demangled type names of a few objects and functions, obtained from `typeinfo().name`. The example also generates several objects of two classes, derived from a common base class. For each object, it is demonstrated that `dynamic_cast` behaves as expected, returning non-NULL when casting to the real object type, and NULL when casting to a different type.
## How to use example
### Configure the project
To run this example, no additional configuration is necessary.
### Build and Flash
Build the project and flash it to the board, then run monitor tool to view serial output:
```
idf.py -p PORT flash monitor
```
(Replace PORT with the name of the serial port to use.)
(To exit the serial monitor, type ``Ctrl-]``.)
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
## Example Output
```
Type names of a few objects:
Type name of std::cout is: std::ostream
Type name of std::cin is: std::istream
Type of app_main is: void ()
Type name of a lambda function is: app_main::{lambda(int, int)#1}
Generating 5 random objects and printing their types:
