Writes data directly to the console input buffer.
Syntax
BOOL WINAPI WriteConsoleInput( __in HANDLE hConsoleInput, __in const INPUT_RECORD *lpBuffer, __in DWORD nLength, __out LPDWORD lpNumberOfEventsWritten );
Parameters
- hConsoleInput [in]
-
A handle to the console input buffer. The handle must have the GENERIC_WRITE access right. For more information, see Console Buffer Security and Access Rights.
- lpBuffer [in]
-
A pointer to an array of INPUT_RECORD structures that contain data to be written to the input buffer.
The storage for this buffer is allocated from a shared heap for the process that is 64 KB in size. The maximum size of the buffer will depend on heap usage.
- nLength [in]
-
The number of input records to be written.
- lpNumberOfEventsWritten [out]
-
A pointer to a variable that receives the number of input records actually written.
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
WriteConsoleInput places input records into the input buffer behind any pending events in the buffer. The input buffer grows dynamically, if necessary, to hold as many events as are written.
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.
