The ReadMultiple method reads specified properties from the current property set.
The numeric count of properties to be specified in the rgpspec array. The value of this parameter can be set to zero; however, that defeats the purpose of the method as no properties are thereby read, regardless of the values set in rgpspec.
An array of PROPSPEC structures specifies which properties are read. Properties can be specified either by a property ID or by an optional string name. It is not necessary to specify properties in any particular order in the array. The array can contain duplicate properties, resulting in duplicate property values on return for simple properties. Nonsimple properties should return access denied on an attempt to open them a second time. The array can contain a mixture of property IDs and string IDs.
Caller-allocated array of a PROPVARIANT structure that, on return, contains the values of the properties specified by the corresponding elements in the rgpspec array. The array must be at least large enough to hold values of the cpspec parameter of the PROPVARIANT structure. The cpspec parameter specifies the number of properties set in the array. The caller is not required to initialize these PROPVARIANT structure values in any specific order. However, the implementation must fill all members correctly on return. If there is no other appropriate value, the implementation must set the vt member of each PROPVARIANT structure to VT_EMPTY.
This method supports the standard return value E_UNEXPECTED, as well as the following:
This function can also return any file system errors or Win32 errors wrapped in an HRESULT data type. For more information, see Error Handling Strategies.
