Examples

EX1

void create_and_terminate_process()
{
    STARTUPINFO            sinfo;
    
    PROCESS_INFORMATION    pinfo;
    
    memset(&sinfo, 0, sizeof(STARTUPINFO));
    memset(&pinfo, 0, sizeof(PROCESS_INFORMATION));
    // test control wShowWindow
    sinfo.dwFlags = STARTF_USESHOWWINDOW;
    sinfo.wShowWindow = SW_SHOWMAXIMIZED;
    BOOL bSucess = CreateProcess("C:\\Windows\\notepad.exe", NULL, NULL, NULL, FALSE, CREATE_DEFAULT_ERROR_MODE, NULL, NULL, &sinfo, &pinfo);
        
    DWORD dwCode;
    
    if(GetExitCodeProcess(pinfo.hProcess, &dwCode))
    {
        if(dwCode == STATUS_PENDING)
            out_str("still alive");
        else
            printf("code = %X\n", dwCode);
    }
    else
        out_str("Failed to get exit code");

    //wait 1 sec
    LT_execute("sec -p 1");
    TerminateProcess(pinfo.hProcess, 2);
    if(GetExitCodeProcess(pinfo.hProcess, &dwCode))
        printf("After terminated, code = %X\n", dwCode);
    else
        out_str("Failed to get exit code");
        
}

Remark

Retrieves the termination status of the specified process.

This function returns immediately.

If the process has not terminated and the function succeeds, the status returned is STATUS_PENDING.

If the process has terminated and the function succeeds, the status returned is one of the following values:

• The exit value specified in the ExitProcess or TerminateProcess function.

• The return value from the main or WinMain function of the process.

• The exception value for an unhandled exception that caused the process to terminate.
