SwapBuffers function (wingdi.h)
The SwapBuffers function exchanges the front and back buffers if the current pixel format for the window referenced by the specified device context includes a back buffer.
Syntax
BOOL SwapBuffers(
HDC unnamedParam1
);
Parameters
unnamedParam1
Specifies a device context. If the current pixel format for the window referenced by this device context includes a back buffer, the function exchanges the front and back buffers.
Return value
If the function succeeds, the return value is TRUE.
If the function fails, the return value is FALSE. To get extended error information, call GetLastError.
Remarks
If the current pixel format for the window referenced by the device context does not include a back buffer, this call has no effect and the content of the back buffer is undefined when the function returns.
With multithread applications, flush the drawing commands in any other threads drawing to the same window before calling SwapBuffers.
