WaitForMultipleObjects doesn't signal for stdin in Wine
The WaitForMultipleObjects
function is primarily used to wait for multiple synchronization objects such as handles to events, mutexes, or threads. It is not designed to wait for standard input (stdin) events.
In the context of Wine, which is a compatibility layer for running Windows applications on Unix-like systems, the behavior of WaitForMultipleObjects
may differ from its behavior on native Windows. It is possible that WaitForMultipleObjects
does not correctly handle stdin events in the Wine environment.
Instead of relying on WaitForMultipleObjects
for stdin events in Wine, you can use other mechanisms to wait for user input on stdin. One option is to use the ReadFile
function with asynchronous I/O or use the GetAsyncKeyState
function to check for keyboard input. These methods allow you to actively check for user input rather than relying on WaitForMultipleObjects
.
Here's an example using GetAsyncKeyState
to wait for a key press on stdin:
cpp#include <iostream>
#include <Windows.h>
int main()
{
while (true)
{
// Check if a key is pressed
if (GetAsyncKeyState(VK_RETURN) & 0x8000)
{
std::cout << "Enter key pressed!" << std::endl;
break;
}
// Sleep to avoid excessive CPU usage
Sleep(100);
}
return 0;
}
In this example, the program continuously checks the state of the Enter key using GetAsyncKeyState
in a loop. When the Enter key is pressed, it breaks out of the loop and prints a message.
Note that the behavior of Wine can vary, and some Windows-specific functionality may not work as expected. It is recommended to consult the Wine documentation or community for specific information regarding the behavior of WaitForMultipleObjects
or other functions in the Wine environment.
