Networking Example — C

Source: apps/c/example_net/src/app.c | WASM Demo{:target="_blank"}

Exercises the full networking stack with a pass/fail test framework: netif configuration, DNS resolution, TCP/UDP sockets, HTTP client (GET/POST/PUT), SNTP time sync, MQTT pub/sub, and embedded HTTP server.

Language-specific patterns

This example uses the unified C API with _create() / _destroy() calls that work in both heap and zero-heap modes.

See the overview for architecture details and the full API list.
