ResumeThread Function
DWORD WINAPI ResumeThread(__inHANDLE hThread);
HANDLE hThread
你需要恢复线程的句柄
使用该函数能够激活线程的运行,使CPU分配资源让线程恢复运行
该函数和SuspendThread(hthread),线程挂起函数对应
消耗线程挂起的时间计数,直到时间计数为0,则激活线程
英文原文:
Decrements a thread's suspend count. When the suspend count is decremented to zero, the execution of the thread is resumed.

Syntax
C++
DWORD WINAPI ResumeThread(__inHANDLE hThread);
hThread [in] A handle to the thread to be restarted. This handle must have the THREAD_SUSPEND_RESUME access right. For more information, see Thread Security and Access Rights.
Return ValueIf the function succeeds, the return value is the thread's previous suspend count.
If the function fails, the return value is (DWORD) -1. To get extended error information, callGetLastError.
TheResumeThreadfunction checks the suspend count of the subject thread. If the suspend count is zero, the thread is not currently suspended.otherwise, the subject thread's suspend count is decremented. If the resulting value is zero, then the execution of the subject thread is resumed.
If the return value is zero, the specified thread was not suspended. If the return value is 1, the specified thread was suspended but was restarted. If the return value is greater than 1, the specified thread is still suspended.
Note that while reporting debug events, all threads within the reporting process are frozen. Debuggers are expected to use theSuspendThreadandResumeThreadfunctions to limit the set of threads that can execute within a process. By suspending all threads in a process except for the one reporting a debug event, it is possible to "single step" a single thread. The other threads are not released by a continue operation if they are suspended.
