This document describes console platform functionality that is no longer a part of our ecosystem roadmap. We do not recommend using this content in new products, but we will continue to support existing usages for the indefinite future. Our preferred modern solution focuses on virtual terminal sequences for maximum compatibility in cross-platform scenarios. You can find more information about this design decision in our classic console vs. virtual terminal document.
Copies a number of characters to consecutive cells of a console screen buffer, beginning at a specified location.
BOOL WINAPI WriteConsoleOutputCharacter( _In_ HANDLE hConsoleOutput, _In_ LPCTSTR lpCharacter, _In_ DWORD nLength, _In_ COORD dwWriteCoord, _Out_ LPDWORD lpNumberOfCharsWritten );
A handle to the console screen buffer. The handle must have the GENERIC_WRITE access right. For more information, see Console Buffer Security and Access Rights.
The characters to be written to the console screen buffer.
The number of characters to be written.
A COORD structure that specifies the character coordinates of the first cell in the console screen buffer to which characters will be written.
A pointer to a variable that receives the number of characters actually written.
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.
If the number of characters to be written to extends beyond the end of the specified row in the console screen buffer, characters are written to the next row. If the number of characters to be written to extends beyond the end of the console screen buffer, characters are written up to the end of the console screen buffer.
The attribute values at the positions written to are not changed.
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. Legacy consumers may also use the chcp or mode con cp select= commands, but it is not recommended for new development.
This API has a virtual terminal equivalent in the text formatting and cursor positioning sequences. Move the cursor to the location to insert, apply the formatting desired, and write out text to fill. There is no equivalent to emit text to an area without also applying the active color formatting. This decision intentionally aligns the Windows platform with other operating systems where the individual client application is expected to remember its own drawn state for further manipulation.
