ID3D12Resource::Unmap method (d3d12.h)
Invalidates the CPU pointer to the specified subresource in the resource.
Syntax
void Unmap(
UINT Subresource,
[in, optional] const D3D12_RANGE *pWrittenRange
);
Parameters
Subresource
Type: UINT
Specifies the index of the subresource.
[in, optional] pWrittenRange
Type: const D3D12_RANGE*
A pointer to a D3D12_RANGE structure that describes the range of memory to unmap.
This indicates the region the CPU might have modified, and the coordinates are subresource-relative. A null pointer indicates the entire subresource might have been modified by the CPU. It is valid to specify the CPU didn't write any data by passing a range where End is less than or equal to Begin.
This parameter is only used by tooling, and not for correctness of the actual unmap operation.
Return value
None
