The OutputDebugString function sends a string from the process being debugged to the debugger by generating an OUTPUT_DEBUG_STRING_EVENT debugging event.OutputDebugString函数通过产生OUTPUT_DEBUG_STRING_EVENT中断由被调试进程向调试器发送字符串。A process can detect whether it is being debugged by calling the IsDebuggerPresent function.进程可以通过调IsDebuggerPresent函数来检测是否处于被调试状态。

The DebugBreak function causes a breakpoint exception in the current process.DebugBreak函数在当前进程引发一个断点异常。 A breakpoint is a location in a program where execution is stopped to allow the developer to examine the program's code, variables, and register values and, as necessary, to make changes, continue execution, or terminate execution.断点是程序停止执行的位置，允许开发人员检测程序的代码、变量、寄存器的值（必要的话进行改变）、继续执行或者终止程序。

The FatalExit function terminates the current process and gives execution control to the debugger, but unlike DebugBreak, it does not generate an exception.函数结束当前进程，把执行控制权交给调试器，但是不像DebugBreak函数，它不产生异常。 This function should only be used as a last resort, because it does not always free the process's memory or close its files.这个函数只能作为最后的手段，因为它并不总是释放进程的内存或者关闭文件。
