This function creates a file moniker based on the specified path.

Syntax

WINOLEAPI CreateFileMoniker(
  LPCOLESTR lpszPathName,
  LPMONIKER FAR* ppmk
);

Parameters

  • lpszPathName
    [in] Pointer to a zero-terminated wide character string (two bytes per character) containing the path on which this moniker is based.
  • ppmk
    [out] Address of IMoniker* pointer variable that receives the interface pointer to the new file moniker. When successful, the function has called IUnknown::AddRef on the file moniker and the caller is responsible for calling IUnknown::Release. When an error occurs, the value of the interface pointer is NULL.

Return Value

This function supports the standard return value E_OUTOFMEMORY, as well as the following:

  • S_OK
    The moniker has been created successfully.
  • MK_E_SYNTAX
    Error in the syntax of a path was encountered while creating a moniker.

Remarks

CreateFileMoniker creates a moniker for an object that is stored in a file.

A moniker provider (an object that provides monikers to other objects) can call this function to create a moniker to identify a file-based object that it controls, and can then make the pointer to this moniker available to other objects.

An object identified by a file moniker must also implement the IPersistFile interface so it can be loaded when a file moniker is bound.

When each object resides in its own file, as in an OLE server application that supports linking only to file-based documents in their entirety, file monikers are the only type of moniker necessary.

To identify objects smaller than a file, the moniker provider must use another type of moniker (such as an item moniker) in addition to file monikers, creating a composite moniker.

Composite monikers would be needed in an OLE server application that supports linking to objects smaller than a document (such as sections of a document or embedded objects).

The lpszPathName can be a relative path, a UNC path (for example, \\server\share\path), or a drive-letter-based path (for example, c:\). If based on a relative path, the resulting moniker must be composed onto another file moniker before it can be bound.

A file moniker can be composed to the right only of another file moniker when the first moniker is based on an absolute path and the other is a relative path, resulting in a single file moniker based on the combination of the two paths.

A moniker composed to the right of another moniker must be a refinement of that moniker, and the file moniker represents the largest unit of storage. To identify objects stored within a file, you would compose other types of monikers (usually item monikers) to the right of a file moniker.
