Function wasmedge_sys::ffi::WasmEdge_CallingFrameGetModuleInstance

pub unsafe extern "C" fn WasmEdge_CallingFrameGetModuleInstance(
    Cxt: *const WasmEdge_CallingFrameContext
) -> *const WasmEdge_ModuleInstanceContext

Get the module instance of the current calling frame.

When a WASM function is executing and start to call a host function, a frame with the module instance which the WASM function belongs to will be pushed onto the stack. And therefore the calling frame context will record that module instance. So in one case that the module instance will be NULL: developers execute the function instance which is a host function and not added into a module instance.

\param Cxt the WasmEdge_CallingFrameContext.

\returns the module instance of the current calling frame.
