c++ - 如何运行时检查代码是否由给定的 asio::strand 实例保护

Question

我想在我的代码中添加一个运行时断言，以检查代码是否受到给定链的保护。

这是一个伪例子:

...

asio::io_service my_io_service;
asio::strand my_strand(my_io_service);

...

void my_async_callback(void) {
// ASSERT that check that my_strand is guarding then code      
ASSERT(?? my_strand ??)
}

...

// With this call my_async_callback is guarded by strand
my_strand.post(&my_async_callback);
...

// With this call my_async_callback is NOT guarded by strand
io_service.post(&my_async_callback);

我想你可能正在寻找

 assert(my_strand.running_in_this_thread());
