使用 WINAPI ReadConsole
我正在尝试使用 WINAPI ReadConsole() 来等待 Win32 控制台应用程序末尾的任何按键。
CONSOLE_READCONSOLE_CONTROL tControl;
char pStr[65536];
DWORD dwBufLen = 1;
DWORD dwCtl;
tControl_c.nLength = sizeof( CONSOLE_READCONSOLE_CONTROL );
tControl_c.nInitialChars = 0;
tControl_c.dwControlKeyState = 0;
tControl_c.dwCtrlWakeupMask = NULL;
pBuf[0] = 0x00;
do
{
ReadConsole( hConsole_c, pStr, (*pBufLen) * sizeof(TCHAR), pBufLen, &tControl );
}
while ( pStr[0] == 0x00 );
该代码执行时不会引发异常。但是，当 ReadConsole() 函数执行时，会标记错误代码 ERROR_INVALID_HANDLE (0x06)。我已验证 hConsole_c 是有效的句柄。有谁知道我做错了什么？我使用的是 Visual C++ 2008 Express 版。谢谢。
I am trying to use the WINAPI ReadConsole() to wait for any keypress at the end of my Win32 console application.
CONSOLE_READCONSOLE_CONTROL tControl;
char pStr[65536];
DWORD dwBufLen = 1;
DWORD dwCtl;
tControl_c.nLength = sizeof( CONSOLE_READCONSOLE_CONTROL );
tControl_c.nInitialChars = 0;
tControl_c.dwControlKeyState = 0;
tControl_c.dwCtrlWakeupMask = NULL;
pBuf[0] = 0x00;
do
{
ReadConsole( hConsole_c, pStr, (*pBufLen) * sizeof(TCHAR), pBufLen, &tControl );
}
while ( pStr[0] == 0x00 );
The code executes without throwing an exception. However, when the ReadConsole() function executes the error code ERROR_INVALID_HANDLE (0x06) is flagged. I have verified hConsole_c to be a valid handle. Does anyone have any insight as to what I am doing wrongly? I am using Visual C++ 2008 Express Edition. Thanks.

对我来说效果很好。我可以让它因 ERROR_INVALID_HANDLE 失败的唯一方法是将 STD_OUTPUT_HANDLE 而不是 STD_INPUT_HANDLE 传递给它。您确定 hConsole_c 是输入句柄吗？
Works fine for me. The only way I could get it to fail with ERROR_INVALID_HANDLE was to pass it the STD_OUTPUT_HANDLE instead of the STD_INPUT_HANDLE. Are you sure hConsole_c is the input handle?
如果您只是想在控制台应用程序结束时等待按键
你为什么不尝试
System("Pause");？If you are just trying to wait for keypress at the end of your console app
why dont you try
System("Pause");?您等待击键的方法非常复杂。使用单个 C 函数调用，有多种方法可以实现此目的：
getch();（或 ISO C++ 符合名称_getch），它与平台无关;system("pause");，这是 Windows 特定的。Your method of waiting for a keystroke is very over-complex. Using single C function calls, there are a couple of ways you can do this:
getch();(or the ISO C++ conformant name,_getch), which is platform independent;system("pause");, which is Windows-specific.
