SwapBuffers
[New
- Windows 95, OEM Service Release 2]
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.
BOOL SwapBuffers(
|
HDC hdc |
// device
context whose buffers get swapped |
|
); |
|
Parameters
hdc
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 Values
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.
