| 释义 | ReadConsoleOutputCharacter 语法： C++ BOOL WINAPI ReadConsoleOutputCharacter( __in HANDLE hConsoleOutput, __out LPTSTR lpCharacter, __in DWORD nLength, __in COORD dwReadCoord, __out LPDWORD lpNumberOfCharsRead ); ReadConsoleOutputCharacter功能 拷贝数从控制台屏幕缓冲区，开始在指定的地点连续单元格中的字符。 参数 hConsoleOutput [in] 句柄到控制台屏幕缓冲区。句柄必须有GENERIC_READ访问的权利。有关更多信息，参见控制台缓冲区安全和访问权限。 lpCharacter [out] 阿一个缓冲区，它接收的字符指针读取控制台屏幕缓冲区。所需的总规模将小于64K的。 nLength [in] 屏幕缓冲区的字符细胞的数目中，读取。缓冲区的大小指出的lpCharacter参数应nLength * sizeof(TCHAR)。 dwReadCoord [in] 的坐标在控制台屏幕缓冲区中，读取的字符，第一个单元格。该坐标结构X成员是列，和Y成员行。 lpNumberOfCharsRead [out] 一个变量，它接收的字符数实际读取的指针。 返回值 如果函数成功，返回值为非零。 如果函数失败，返回值是零。为了获得更多错误信息，调用GetLastError。 备注 如果字符数，可以从扩展，字符是从下一行读取超出指定的屏幕缓冲区的行结束。如果字符数，可以从阅读延伸是超出了控制台屏幕缓冲区，字符直至控制台屏幕缓冲区年底结束。 此函数使用任何Unicode字符或8位字符从控制台的当前代码页。控制台的代码页默认最初系统的OEM代码页。要更改控制台的代码页，使用SetConsoleCP或SetConsoleOutputCP功能，或使用chcp处长或节能模式选择=命令。 要求： 最低支持：client－Windows 2000专业版 最低支持server－Windows 2000服务器 HeaderWincon.h(头文件：winuser.h) LibraryKernel32.lib DLLKernel32.dll Unicode和ANSI namesReadConsoleOutputCharacterW(Unicode)和ReadConsoleOutputCharacterA(ANSI)的 参见 控制台函数 COORD 低级别控制台输出函数 ReadConsoleOutput ReadConsoleOutputAttribute SetConsoleCP SetConsoleOutputCP WriteConsoleOutput WriteConsoleOutputAttribute WriteConsoleOutputCharacter 如果有任何问题和意见，请发送给微软(wsddocfb@microsoft.com) 生成日期：2009年8月27日 ＝＝英文原文＝＝ReadConsoleOutputCharacter Function Copies a number of characters from consecutive cells of a console screen buffer, beginning at a specified location. Syntax C++ BOOL WINAPI ReadConsoleOutputCharacter( __in HANDLE hConsoleOutput, __out LPTSTR lpCharacter, __in DWORD nLength, __in COORD dwReadCoord, __out LPDWORD lpNumberOfCharsRead ); Parameters hConsoleOutput [in] A handle to the console screen buffer. The handle must have the GENERIC_READ access right. For more information, see Console Buffer Security and Access Rights . lpCharacter [out] A pointer to a buffer that receives the characters read from the console screen buffer. The total size required will be less than 64K. nLength [in] The number of screen buffer character cells from which to read. The size of the buffer pointed to by the lpCharacter parameter should be nLength * sizeof(TCHAR). dwReadCoord [in] The coordinates of the first cell in the console screen buffer from which to read, in characters. The X member of the COORD structure is the column, and the Y member is the row. lpNumberOfCharsRead [out] A pointer to a variable that receives the number of characters actually read. Return Value If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call GetLastError . Remarks If the number of characters to be read from extends beyond the end of the specified screen buffer row, characters are read from the next row. If the number of characters to be read from extends beyond the end of the console screen buffer, characters up to the end of the console screen buffer are read. This function uses either Unicode characters or 8-bit characters from the console's current code page. The console's code page defaults initially to the system's OEM code page. To change the console's code page, use the SetConsoleCP or SetConsoleOutputCP functions, or use the chcp or mode con cp select= commands.
