A small example of a Windows Thread

# Include <iostream> <br/> using namespace STD; <br/> # include "windows. H "<br/> extern DWORD winapi threadfunc (lpvoid); <br/> int main (INT argc, char * argv []) <br/>{</P> <p> DWORD threadid; <br/> cout <"test thread" <Endl; <br/> handle hthread = :: createthread (null, 0, threadfunc, 0, 0, & threadid); <br/> for (INT I = 0; I <10; I ++) <br/>{< br/> cout <Endl <"main thread" <I <Endl; <br/>}< br/> return 0; <br/>}< br/> DWORD winapi threadfunc (lpvoid) <br/>{< br/> int I = 0; <br/> while (true) <br/>{< br/> cout <"thread func" <I ++ <Endl; <br/>}< br/>}

 

Running result:

Test thread

Thread funcmain thread 11

Thread func

Thread funcmain thread 32

Thread funcmain thread 43
Thread func

This small example describes two points:

1. When the main thread ends, the thread also ends.

2 because cout writes data in a buffer zone, to ensure the correctness of the result, a critical section must be added for mutual exclusion.
