Causes the calling thread to yield execution to another thread that is ready to run on the current processor. The operating system selects the next thread to be executed. Syntax C++ BOOLSwitchToThread(); Return
现在我们采用C++11的function,将函数作为Thread类的成员,用户只需要将function对象传入线程即可,所以Thread的声明中,应该含有一个function成员变量。 类的声明如下: #ifndef THREAD_H_#defineTHREAD_H_#include<boost/noncopyable.hpp>#include<functional>#include<pthread.h>classThread : boost::noncopyable {public: t...
This function returns immediately. If the specified thread has not terminated and the function succeeds, the status returned isSTILL_ACTIVE. If the thread has terminated and the function succeeds, the status returned is one of the following values: ...
BOOL IsGUIThread( [in] BOOL bConvert ); Parameters [in] bConvert Type: BOOL If TRUE and the thread is not a GUI thread, convert the thread to a GUI thread. Return value Type: BOOL The function returns a nonzero value in the following situations: If the calling thread is already a...
Use the public functionGetThreadIOPendingFlaginstead to obtain this information. If this parameter is theThreadQuerySetWin32StartAddressvalue of theTHREADINFOCLASSenumeration, the function returns the start address of the thread. Note that on versions of Windows prior to Windows Vista, the returned ...
this the current component-side thread API: typedef void(*hal_funct_t)(void * arg, long period) int hal_export_funct(const char *name, hal_funct_t funct, void *arg, int uses_fp, int reentrant, int comp_id) Problems: period is a setup tim...
1. Callable Using Function Object In this technique, a function object can be set as callable. For that, a class is needed, and operator () has to be overloaded inside that class. The overloaded methods contain the program that must be executed when the thread is created. ...

在上面的示例中,threadFunction是一个线程执行函数,它简单地输出一条消息。在main函数中,我们创建了一个std::thread对象t,并将threadFunction作为构造函数的参数。这会导致一个新的线程启动,并执行threadFunction函数。t.join()调用会阻塞主线程,直到新线程完成执行。 如果你想要线程执行函数接受参数,你可以将这些参数...
