Investigate the guest C++ runtime

The SDK supplies a C++ runtime for code that executes inside Symbian. The project chooses a target architecture and links only the library profiles it uses. Guest code has exceptions disabled by default; application and library errors use explicit status results.

Choose one question

Goal	Start with
Use strings, containers or clocks	C++ capabilities
Add a timer or bounded asynchronous task	Concurrency
Link a native library or DLL	Library targets
Explore startup, imports and ABI behavior	Runtime reference

The runtime capability page describes the library profiles and restrictions. Run the smallest relevant example before adding a feature to your application.

Build and inspect a small runtime program

From a prepared source checkout, build the string/vector diagnostic probe with the selected SDK:

symbian build --project probes/runtime_probe --output .symbian/runtime-probe
symbian inspect --format e32 .symbian/runtime-probe/runtime_probe.exe

Keep the matching ELF for debugging. Run the executable in a disposable emulator instance with compatible firmware and inspect its native exit reason. The probe exercises repeated allocation and destruction and includes separate allocation-failure controls.
