RestoreDC function

Applies to: desktop apps only

The RestoreDC function restores a device context (DC) to the specified state. The DC is restored by popping state information off a stack created by earlier calls to the SaveDC function.

Syntax

Copy

BOOL RestoreDC(
  __in  HDC hdc,
  __in  int nSavedDC
);

Parameters

hdc [in]: A handle to the DC.
nSavedDC [in]: The saved state to be restored. If this parameter is positive, nSavedDC represents a specific instance of the state to be restored. If this parameter is negative, nSavedDC represents an instance relative to the current state. For example, -1 restores the most recently saved state.

Return value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero.

Remarks

The stack can contain the state information for several instances of the DC. If the state specified by the specified parameter is not at the top of the stack, RestoreDC deletes all state information between the top of the stack and the specified instance.
