Windows API Reference - Functions - MsgWaitForMultipleObjects

Introduction

The MsgWaitForMultipleObjects function allows you to wait for multiple objects to be ready before proceeding with an operation.

It takes a pointer to the object and an integer representing the timeout. The function waits until the specified object is ready.

Usage

Here's a simple example:

            
                MsgWaitForMultipleObjects(pointer, timeout) {
                    // Wait for the specified timeout.
                    return new Promise((resolve) => {
                        setTimeout(() => {
                            resolve();
                        }, timeout);
                    });
                }
            
            

This example just returns a promise to simulate the waiting.

Example

Let's say we have a 'Message' object that needs to be processed after a certain delay. We'll use MsgWaitForMultipleObjects to wait for it.

const message = new Message(); const waitTime = 2000; const result = MsgWaitForMultipleObjects(message, waitTime); console.log(result);

The `result` variable will be `true` if the message is ready and `false` otherwise.

Important Considerations

This function is crucial for asynchronous operations where you need to synchronize multiple steps. Always handle the promise returned by the function to ensure proper error handling.

Consider using a timeout to gracefully handle the case where the object is not ready.
