mutable boost::mutex 是否可以将锁定和等待功能分开？
所以我有像 read 这样的函数，可以从多个线程同时调用。而且我还有一个写入函数，需要锁定所有读取函数。在哪里可以获得创建此类架构的示例？
我知道我们可以：
mutable boost::mutex the_read_mutex;
mutable boost::mutex the_write_mutex;
和：
void write()
{
// make all new readers wait and wait for all other currently running read threads();
}
void read()
{
// do not make all new readers wait, and wait for all currently running write thread()
}
那么如何做这样的事情呢？
So I have functions like read that can be called at the same time from multiple threads. but also I have a function to write that needs to lock all that read functions. Where to get example of creating such archetecture?
I get that we can have:
mutable boost::mutex the_read_mutex;
mutable boost::mutex the_write_mutex;
and:
void write()
{
// make all new readers wait and wait for all other currently running read threads();
}
void read()
{
// do not make all new readers wait, and wait for all currently running write thread()
}
So how to do such thing?
