Parameters
- pwcsName
Type: System.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: System.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: System.IntPtr
Must be NULL. A non-NULL value will return STG_E_INVALIDPARAMETER.
- reserved
Type: System.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.
