RtlIsPartialPlaceholderFileInfo function

Description

The RtlIsPartialPlaceholderFileInfo routine determines if a file is a known type of placeholder, based on the information returned by NtQueryInformationFile or NtQueryDirectoryFile.

Parameters

InfoBuffer [in]

Specifies a pointer to a caller-allocated buffer which contains information about the file object. If this is from a call to NtQueryDirectoryFile, this may point to the first or any subsequent subsequent entry in the buffer (found by walking the buffer).

InfoClass [in]

Specifies which File Information class to use to query InfoBuffer.

IsPartialPlaceholder [out]

IsPartialPlaceholder is a pointer to a boolean which returns TRUE if the file or directory is a placeholder. It returns FALSE if either the file or directory is not a placeholder or is a full placeholder. Returns undefined on failure.

Return value

Returns STATUS_SUCCESS if IsPartialPlaceholder is valid and not undefined.

Remarks

If InfoBuffer is from a call to NtQueryDirectoryFile, this may point to the first or any subsequent subsequent entry in the buffer which is found by walking the buffer.
