AUI_THREADPOOL

Executes following {} block asynchronously in the global thread pool. Unlike AUI_THREADPOOL_X, does now allow to set lambda's capture. Lambda's capture is [=].

Header:	#include <AUI/Util/kAUI.h>
CMake:	aui_link(my_target PUBLIC aui::core)

Definition

#define AUI_THREADPOOL AThreadPool::global() * [=]()

Detailed Description

When AFuture is destroyed, the corresponding AUI_THREADPOOL task is either cancelled or removed from the execution queue. Use AFutureSet or AAsyncHolder to keep multiple AFuture alive.

Example without a return value:

auto task = AUI_THREADPOOL {
  AThread::sleep(1000); // a long task
};

Example with a return value:

auto futureStatus = AUI_THREADPOOL {
  int status;
  ...
  AThread::sleep(1000); // a long task
  ...
  return status;
};
int status = *futureStatus;

Lambda operators are supported:

auto futureStatus = AUI_THREADPOOL mutable noexcept {
  int status;
  ...
  AThread::sleep(1000); // a long task
  ...
  return status;
};
int status = *futureStatus;
