If this parameter is NULL, the thread identifier is not returned. The flags that control the creation of the thread.Ī pointer to a variable that receives the thread identifier. This pointer represents the starting address of the thread.Ī pointer to a variable to be passed to the thread. If this parameter is zero, the new thread uses the default size for the executable.Ī pointer to the application-defined function to be executed by the thread. The system rounds this value to the nearest page. The ACLs in the default security descriptor for a thread come from the primary token of the creator. If lpThreadAttributes is NULL, the thread gets a default security descriptor. The lpSecurityDescriptor member of the structure specifies a security descriptor for the new thread. If lpThreadAttributes is NULL, the handle cannot be inherited. _in LPTHREAD_START_ROUTINE lpStartAddress,Ī pointer to a SECURITY_ATTRIBUTES structure that determines whether the returned handle can be inherited by child processes. _in_opt LPSECURITY_ATTRIBUTES lpThreadAttributes,

The following syntax shows the parameters passed to CreateThread(). The function call we use to create a child thread is CreateThread().

The most basic Windows applications start with a single thread. The address of this function (that is, the entry point to the thread) is specified in threadFunc.īy typing a character 'q', we can end the program. Execution of the thread continues until the thread function returns. The 3rd argument of CreateThread( ) function, myThread is that thread function. HANDLE myHandle = CreateThread(0, 0, myThread, &m圜ounter, 0, &myThreadID ) Įach thread of execution begins with a call to a function, called the thread function, within the creating process. Unsigned int& m圜ounter = *((unsigned int*)lpParameter) If this integer value is zero, then the thread will be given a stack that is the same size as the creating thread.ĭWORD WINAPI myThread(LPVOID lpParameter) You can specify the size of the new thread's stack in bytes using the stackSize parameter which is the 2nd argument of CreateThread( ) function in the example below.

To create a thread, the Windows API supplies the CreateThread( ) function.Įach thread has its own stack (see thread vs processes). To use Windows multithreading functions, we must include in our program. The main thread spawns a new thread to increment the m圜ounter inside myThread function, while the main thread keeps waiting for a character input ( getchar()) from the user, and prints out counter value whenever we type other than 'q' character: In fact, the threads in a Win32 program will be competing for the CPU with threads in other programs and with system threads, and these other threads may have higher priorities. We will assume that the OS will give a time slice to each program thread, in round-robin fashion. Every Win32 process has at least one thread, which we call as the main thread.
