Function Documentation

◆ __declspec()

CPP_EXTERN __declspec ( selectany ) const

◆ _Success_()

_ACRTIMP _Success_ ( return )

Deletes the virtual mapping and optionally gives back the page & dirty bit.

Parameters

Process	- The process this address belongs to, or NULL if system address.
Address	- The address to unmap.
WasDirty	- Optional param receiving the dirty bit of the PTE.
Page	- Optional param receiving the page number previously mapped to this address.

Returns: Whether there was actually a page mapped at the given address.

Deletes the virtual mapping and optionally gives back the page & dirty bit.

Parameters

	[in,opt]	hDC An optional GDI device context handle.
[in]	hFont	The GDI handle to the font.
[out]	Height	In case of success, receives the cell height size (in pixels).
[out]	Width	In case of success, receives the cell height size (in pixels).

Returns: TRUE if success, FALSE in case of failure.
