Win32 equivalent API for pthread_cond_wait
The Win32 equivalent API for pthread_cond_wait
from the POSIX threads library is the WaitForSingleObject
or WaitForMultipleObjects
functions in the Windows API. These functions allow a thread to wait for a synchronization object to be signaled.
Here's an example of how you can use WaitForSingleObject
as a replacement for pthread_cond_wait
:
c#include <windows.h>
// ...
// Create a manual-reset event
HANDLE condition = CreateEvent(NULL, TRUE, FALSE, NULL);
// ...
// Wait for the condition to be signaled
DWORD result = WaitForSingleObject(condition, INFINITE);
if (result == WAIT_OBJECT_0) {
// The condition was signaled
// Continue with the desired action
} else {
// An error occurred or the wait was abandoned
// Handle the error condition
}
// ...
// Signal the condition to wake up the waiting thread(s)
SetEvent(condition);
// ...
// Cleanup: Close the condition handle
CloseHandle(condition);
In this example, CreateEvent
is used to create a manual-reset event (condition
). The WaitForSingleObject
function is called to wait for the event to be signaled. The INFINITE
parameter indicates that the function should wait indefinitely until the event is signaled.
After the condition is signaled, the waiting thread(s) can proceed with the desired action. To signal the condition, the SetEvent
function is used.
Finally, remember to close the condition handle using CloseHandle
to release any associated resources.
Keep in mind that this is a basic example, and you may need to adapt it to your specific use case and synchronization requirements. Additionally, Windows provides various other synchronization objects like mutexes, semaphores, and condition variables that may be more suitable depending on your scenario.
