CF_PLACEHOLDER_CREATE_INFO structure (cfapi.h)
Contains placeholder information for creating new placeholder files or directories.
Syntax
typedef struct CF_PLACEHOLDER_CREATE_INFO {
LPCWSTR RelativeFileName;
CF_FS_METADATA FsMetadata;
LPCVOID FileIdentity;
DWORD FileIdentityLength;
CF_PLACEHOLDER_CREATE_FLAGS Flags;
HRESULT Result;
USN CreateUsn;
} CF_PLACEHOLDER_CREATE_INFO;
Members
RelativeFileName
The name of the child placeholder file or directory to be created. It should consist only of the file or directory name.
For example, if the sync root of the provider is C:\SyncRoot then to create a placeholder named placeholder.txt in a subdirectory of the sync root, call the CfCreatePlaceholders function with BaseDirectoryPath equal to C:\SyncRoot\SubDirectory
and set the RelativePathName field of the CF_PLACEHOLDER_CREATE_INFO to placeholder.txt
.
FsMetadata
File system metadata to be created with the placeholder, including all timestamps, file attributes and file size (optional for directories).
FileIdentity
A user mode buffer containing file information supplied by the sync provider. The FileIdentity blob should not exceed CF_PLACEHOLDER_MAX_FILE_IDENTITY_LENGTH (defined to 4KB) in size. FileIdentity gets passed back to the sync provider in all callbacks. This is required for files (not for directories).
FileIdentityLength
Length, in bytes, of the FileIdentity.
Flags
Flags for specifying placeholder creation behavior. See CF_PLACEHOLDER_CREATE_FLAGS for more information.
Result
The result of placeholder creation. On successful creation, the value is STATUS_OK.
CreateUsn
The final USN value after create actions are performed.
