问题描述

我想要createThread(LPSECURITY_ATTRIBUTES lpThreadAttributes，SIZE_T dwStackSize，LPTHREAD_START_ROUTINE lpStartAddress，LPVOID lpParameter，DWORD dwCreationFlags，LPDWORD lpThreadId);

I want createThread(LPSECURITY_ATTRIBUTES lpThreadAttributes, SIZE_T dwStackSize, LPTHREAD_START_ROUTINE lpStartAddress, LPVOID lpParameter, DWORD dwCreationFlags, LPDWORD lpThreadId);
