wasmtime_component_func_type_clone()

WASM_API_EXTERN wasmtime_component_func_type_t * wasmtime_component_func_type_clone

(

const wasmtime_component_func_type_t *

ty

)

Clones a component function type.

The pointer returned from this function must be deallocated with wasmtime_component_func_type_delete.

wasmtime_component_func_type_param_nth()

WASM_API_EXTERN bool wasmtime_component_func_type_param_nth	(	const wasmtime_component_func_type_t *	ty,
		size_t	nth,
		const char **	name_ret,
		size_t *	name_len_ret,
		wasmtime_component_valtype_t *	type_ret
	)

Retrieves the nth parameter.

The type_ret return value must be deallocated with wasmtime_component_valtype_delete.

wasmtime_component_func_type_result()

WASM_API_EXTERN bool wasmtime_component_func_type_result	(	const wasmtime_component_func_type_t *	ty,
		wasmtime_component_valtype_t *	type_ret
	)

Returns the result, if any, of this component function type.

The type_ret return value must be deallocated with wasmtime_component_valtype_delete.
