Multithreading – STD:: this_ Thread:: yield() usage?

Can someone provide STD:: this in C application_ A real example of the use of thread:: yield()?

Solution

I used yield in the implementation of STD:: lock. Here I find:

http://llvm.org/svn/llvm-project/libcxx/trunk/include/mutex

It has been proved that when multiple locks / mutexes are locked at one time, if one lock / mutex is not obtained, you can use yield to speed up the application before trying locks / mutexes in different order

In this source code, I'm actually calling sched_ yield(). But this is just to get the header dependency the way I want On this platform, STD:: this_ Thread:: yield() is just a reference to sched_ Call to yield():
