write()写文件函数 原形：int write(int handle,char *buf,unsigned len)功能：将缓冲区的数据写入与handle相联的文件或设备中，handle是从creat、open、dup或dup2调用中得到的文件句柄。对于磁盘或磁盘文件，写操作从当前文件指针处开始,对于用O_APPEND选项打开的文件，写数据之前，文件指针指向EOF；对于...
When the buffer is finished, the WHDR_DONE bit is set in thedwFlagsmember of theWAVEHDRstructure. The buffer must be prepared with thewaveOutPrepareHeaderfunction before it is passed towaveOutWrite. Unless the device is paused by calling thewaveOutPausefunction, playback begins when the first dat...
If the call to this function occurs in user mode, you should use the name "NtWriteFile" instead of "ZwWriteFile".For calls from kernel-mode drivers, the NtXxx and ZwXxx versions of a Windows Native System Services routine can behave differently in the way that they handle and interpret ...

This function took no arguments and simply turned on DPI awareness, so to speak. This was before per-monitor awareness, so this was a simple binary state. Either you’re DPI-aware or you’re not. Windows 8.1 introduced a new function called SetProcessDpiAwareness that provides ...
You can enable this function via a hidden setting in Windows 7 also for USB storage media and SD cards to improve the flow. Achieve a clearly noticeable performance benefit for USB devices that are referred to as the local disk — this applies esp...

write_data()这个函数没有事先声明过原型，前面也找不到这个实体函数，所以要么把enter()函数体移到前面，要么在前面放个原型声明。应该
