Function Documentation

wasmtime_engine_clone()

wasm_engine_t * wasmtime_engine_clone

(

wasm_engine_t *

engine

)

Create a new reference to the same underlying engine.

This function clones the reference-counted pointer to the internal object, and must be freed using wasm_engine_delete.

wasmtime_engine_increment_epoch()

void wasmtime_engine_increment_epoch

(

wasm_engine_t *

engine

)

Increments the engine-local epoch variable.

This function will increment the engine's current epoch which can be used to force WebAssembly code to trap if the current epoch goes beyond the wasmtime_store_t configured epoch deadline.

This function is safe to call from any thread, and it is also async-signal-safe.

See also wasmtime_config_epoch_interruption_set.
