Networking Example — C

Source: apps/c/example_net/src/app.c | WASM Demo

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 heap-mode C API with _create() / _destroy() calls. For zero-heap builds, switch to _init() / _deinit() with caller-supplied storage or use OVE_*_DEFINE_STATIC() at file scope (the latter also works in heap mode).

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