讲一下SystemParametersInfo(看不懂msdn上的解释)
我读了一个程序中有:
SystemParametersInfo(SPI_SETSCREENSAVERRUNNING,1,NULL,0);
表示"系统热键被屏蔽"
(不知道是什么意思)
查了msdn上面讲
This function is intended for use with applications, such as the Control Panel, that allow the user to customize the Windows environment.(不能理解,帮我解释一下)
而那个参数SPI_SETSCREENSAVERRUNNING
:Windows 95 and later: Used internally; applications should not use this flag.
(也不理解)
所以请好心人帮我讲一下这个函数的功能(说个大概就行)
