Function Documentation

PopulateFileInfo()

STATIC EFI_STATUS PopulateFileInfo	(	IN VIRTIO_FS_FUSE_DIRENTPLUS_RESPONSE *	Dirent,
		IN UINTN	SingleFileInfoSize,
		OUT EFI_FILE_INFO *	FileInfo
	)

Populate a caller-allocated EFI_FILE_INFO object from VIRTIO_FS_FUSE_DIRENTPLUS_RESPONSE.

Parameters

[in]	Dirent	The entry read from the directory stream. The caller is responsible for ensuring that Dirent->Namelen describe valid storage.
[in]	SingleFileInfoSize	The allocated size of FileInfo.
[out]	FileInfo	The EFI_FILE_INFO object to populate. On success, all fields in FileInfo will be updated, setting FileInfo->Size to the actually used size (which will not exceed SingleFileInfoSize).

Return values

EFI_SUCCESS

FileInfo has been filled in.

Returns

Error codes propagated from VirtioFsFuseDirentPlusToEfiFileInfo() and VirtioFsFuseAttrToEfiFileInfo(). The contents of FileInfo are indeterminate.
