ReleaseDC
The ReleaseDC
function releases a device context (DC), freeing it for use by other
applications. The effect of the ReleaseDC function depends on the type
of device context. It frees only common and window device contexts. It has no
effect on class or private device contexts.
int ReleaseDC(
|
HWND hWnd, |
// handle of window
|
|
HDC hDC |
// handle of device
context |
|
); |
|
Parameters
hWnd
Identifies
the window whose device context is to be released.
hDC
Identifies
the device context to be released.
Return Values
The return
value specifies whether the device context is released. If the device context
is released, the return value is 1.
If the device
context is not released, the return value is zero.
Remarks
The
application must call the ReleaseDC function for each call to the GetWindowDC
function and for each call to the GetDC function that retrieves a common
device context.
An
application cannot use the ReleaseDC function to release a device
context that was created by calling the CreateDC function; instead, it must
use the DeleteDC function.
