how to terminate a process created by CreateProcess()?


I have created a process using CreateProcess(). This is the code:

STARTUPINFO si = {0};
PROCESS_INFORMATION pi = {0};
result = CreateProcess("C:\\AP\\DatabaseBase\\dbntsrv.exe", NULL, NULL, NULL, FALSE, 0, NULL, "C:\\ADP\\SQLBase", &si, &pi)

How can I get the Handle and processId of this specific process? And eventually use it to close this process?
Thank You.


Solution

  • In the struct pi you get:

    typedef struct _PROCESS_INFORMATION {
        HANDLE hProcess;
        HANDLE hThread;
        DWORD  dwProcessId;
        DWORD  dwThreadId;
    } PROCESS_INFORMATION, *LPPROCESS_INFORMATION;
    

    The first parameter is the handle to the process.

    You can use that handle to end the process:

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

    hProcess [in]
    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 [in]
    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.
