Parameters

• pwcsName
  Type: String

  A pointer to a wide character null-terminated Unicode string that contains the name of the storage object to open. The 000 through 01f characters, serving as the first character of the stream/storage name, are reserved for use by OLE. This is a compound file restriction, not a structured storage restriction. It is ignored if pstgPriority is non-NULL.

• pstgPriority
  Type: Microsoft.VisualStudio.OLE.Interop.IStorage

  Must be NULL. A non-NULL value will return STG_E_INVALIDPARAMETER.

• grfMode
  Type: UInt32

  Specifies the access mode to use when opening the storage object. For descriptions of the possible values, see STGM Constants. Other modes you choose must at least specify STGM_SHARE_EXCLUSIVE when calling this method.

• snbExclude
  Type: IntPtr

  Must be NULL. A non-NULL value will return STG_E_INVALIDPARAMETER.

• reserved
  Type: UInt32

  Reserved for future use; must be zero.

• ppstg
  Type: Microsoft.VisualStudio.OLE.Interop.IStorage%

  When successful, pointer to the location of an IStorage pointer to the opened storage object. This parameter is set to NULL if an error occurs.
