Detailed Description

Immutable raw-fd CoreGraphics direct provider implementation.

Implements descriptor encoding, bounded positional RGB565 reads, CoreGraphics release ownership, and a non-Apple contract stub for the immutable presentation-provider boundary.

CGDataProviderRef priv_board_view_provider_create	(	int	snapshot_fd,
		size_t	provider_bytes )

Transfer one sealed RGB565 descriptor into a lazy RGB888 provider.

Parameters

[in]	snapshot_fd	Owned immutable descriptor; ownership always transfers.
[in]	provider_bytes	Exact virtual 32-bit output length.

Returns: CoreGraphics provider, or NULL after closing snapshot_fd.

Postcondition: The provider release callback closes snapshot_fd exactly once.

Note: CoreGraphics supplies every destination byte buffer; no client allocation.

Since: 0.1.0

Transfer one sealed rgb565 descriptor into a lazy rgb888 provider; this step is contained within the board view provider model and uses bounded caller or module-owned storage.

Return values

value The operation-specific board view provider create value.

Precondition: Arguments satisfy the ranges documented for board view provider create.; The call executes on the emulator's single owning thread.

Postcondition: Ownership of caller-supplied storage is unchanged.
