如何運行時檢查代碼是否由給定的asio :: strand實例保護

Question

我想在我的代碼中添加一個運行時斷言，以檢查代碼是否受給定鏈保護。

這是一個偽示例：

...

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);

Answer 1

我想您可能正在尋找

 assert(my_strand.running_in_this_thread());
