The ReadConsole function reads character input from the console input buffer and removes it from the buffer.
BOOL ReadConsole(
HANDLE hConsoleInput, |
// handle of a console input buffer |
LPVOID lpBuffer, |
// address of buffer to receive data |
DWORD nNumberOfCharsToRead, |
// number of characters to read |
LPDWORD lpNumberOfCharsRead, |
// address of number of characters read |
LPVOID lpReserved |
// reserved |
); |
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.
ReadConsole reads keyboard input from a console’s input buffer. It behaves like the ReadFile function, except that it can read in either Unicode (wide-character) or ANSI mode. To have applications that maintain a single set of sources compatible with both modes, use ReadConsole rather than ReadFile. Although ReadConsole can only be used with a console input buffer handle, ReadFile can be used with other handles (such as files or pipes). ReadConsole fails if used with a standard handle that has been redirected to be something other than a console handle.
All of the input modes that affect the behavior of ReadFile have the same effect on ReadConsole. To retrieve and set the input modes of a console input buffer, use the GetConsoleMode and SetConsoleMode functions.
If the input buffer contains input events other than keyboard events (such as mouse events or window-resizing events), they are discarded. Those events can only be read by using the ReadConsoleInput function.
Windows NT: This function uses either Unicode characters or 8-bit characters from the console's current codepage. The console's codepage defaults initially to the system's OEM codepage. To change the console's codepage, use the SetConsoleCP or SetConsoleOutputCP functions, or use the chcp or mode con cp select= commands.
