尝试锁定 Windows
在pthread库中可以找到非阻塞函数：
int pthread_mutex_trylock(pthread_mutex_t *mutex);
我可以在Windows中找到类似的东西吗？
in pthread library it is possible to find non blocking function:
int pthread_mutex_trylock(pthread_mutex_t *mutex);
can I find something similar in Windows?

如果您使用锁的关键部分，则等效内容为
TryEnterCriticalSection()。如果您使用互斥锁作为锁，则等效方法是调用
WaitForSingleObject()传递0作为超时。如果您不熟悉 Windows 同步对象，请不要被愚弄而更喜欢互斥体，因为它有一个您在 pthread 背景中最熟悉的名称。只要您的同步在进程内，关键部分就会更高效且更易于使用。
If you are using a critical section for your lock then the equivalent is
TryEnterCriticalSection().If you are using a mutex for your lock then the equivalent is to call
WaitForSingleObject()passing0as the timeout.If you are unfamiliar with Windows synchronisation objects, don't be fooled into preferring the mutex because it has a name that you are most familiar with from a pthreads background. So long as your synchronisation is within process, critical sections are more efficient and easier to use.
您可以检查 Boost 库。他们有一个叫做shareable_locks的东西。< br>
这是 Boost Interprocess Library 的一部分，适用于Windows 和 Unix。
You could check the Boost library. They have something called shareable_locks.
This is part of the Boost Interprocess Library which works in both Windows and Unix.
