You can change it with CPPHTTPLIB_THREAD_POOL_COUNT.If you want to set the thread count at runtime, there is no convenient way... But here is how.svr.new_task_queue = [] { return new ThreadPool(12); }; You can also provide an optional parameter to limit the maximum number of ...
The followings are built-in mappings: [!WARNING] These static file server methods are not thread-safe. File request handler // The handler is called right before the response is sent to a clientsvr.set_file_request_handler([](constRequest &req, Response &res) { ... }); Logging svr.se...
So basically when you call the ros::spinOnce() function, a single-thread spinner is created and its spin method is called once using the default callback queue (see init.cpp from roscpp). And to finish, when you create a Subscriber, you pass it a NodeHandle and each NodeHandle has an...
The thread_queue class in the library is a thread-safe queue that you can use for this. To route incoming messages by topic: Use an instance of the (topic_matcher)[https://github.com/eclipse/paho.mqtt.cpp/blob/master/include/mqtt/topic_matcher.h] collection to create a collection of ...
A thread-safe queue forstd::functionitems (e. g. executable code). The main use case is queuing execution in a different thread, e. g. a worker thread can use the queue to post UI actions on the UI thread. CConsumerBlockingQueue ...
