Embed WAMR into software production
A typical WAMR API usage is shown below (some return value checks are ignored):
static char global_heap_buf[512 * 1024];
char *buffer, error_buf[128];
wasm_module_t module;
wasm_module_inst_t module_inst;
wasm_function_inst_t func;
wasm_exec_env_t exec_env;
uint32 argv[2], size, stack_size = 8092, heap_size = 8092;
bh_memory_init_with_pool(global_heap_buf, sizeof(global_heap_buf));
wasm_runtime_init();
buffer = read_wasm_binary_to_buffer(…, &size);
module = wasm_runtime_load(buffer, size, error_buf, sizeof(error_buf));
module_inst = wasm_runtime_instantiate(module, stack_size, heap_size,
error_buf, sizeof(error_buf));
func = wasm_runtime_lookup_function(module_inst, "fib", "(i32)i32");
exec_env = wasm_runtime_create_exec_env(module_inst, stack_size);
argv[0] = 8;
if (wasm_runtime_call_wasm(exec_env, func, 1, argv_buf) ) {
/* the return value is stored in argv[0] */
printf("fib function return: %d\n", argv[0]);
}
else {
printf("%s\n", wasm_runtime_get_exception(module_inst));
}
wasm_runtime_destroy_exec_env(exec_env);
wasm_runtime_deinstantiate(module_inst);
wasm_runtime_unload(module);
wasm_runtime_destroy();
bh_memory_destroy();
