TerminateProcess Function

大家好，又见面了，我是你们的朋友全栈君。

Terminates the specified process and all of its threads.

BOOL WINAPI TerminateProcess(
  __in          HANDLE hProcess,
  __in          UINT uExitCode
);

Parameters

hProcess

A handle to the process to be terminated.

The handle must have the PROCESS_TERMINATE access right. For more information, see Process Security and Access Rights.

uExitCode

The exit code to be used by the process and threads terminated as a result of this call. Use the GetExitCodeProcess function to retrieve a process’s exit value. Use the GetExitCodeThread function to retrieve a thread’s exit value.

Return Value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError .

Remarks

The TerminateProcess function is used to unconditionally cause a process to exit. The state of global data maintained by dynamic-link libraries (DLLs) may be compromised if TerminateProcess is used rather than ExitProcess.

TerminateProcess initiates termination and returns immediately. This stops execution of all threads within the process and requests cancellation of all pending I/O. The terminated process cannot exit until all pending I/O has been completed or canceled.

A process cannot prevent itself from being terminated.
