A _bstr_t object encapsulates the BSTR data type. The class manages resource allocation and deallocation through function calls to SysAllocString and SysFreeString and other BSTR APIs when appropriate. The _bstr_t class uses reference counting to avoid excessive overhead.
Constructs a _bstr_t object.
Copies a BSTR into the BSTR wrapped by a _bstr_t.
Links a _bstr_t wrapper to a BSTR.
Constructs a copy of the encapsulated BSTR.
Returns the BSTR wrapped by a _bstr_t and detaches the BSTR from the _bstr_t.
Points to the BSTR wrapped by a _bstr_t.
Points to the beginning of the BSTR wrapped by the _bstr_t.
Returns the number of characters in the _bstr_t.
Assigns a new value to an existing _bstr_t object.
Appends characters to the end of the _bstr_t object.
Concatenates two strings.
Checks if the encapsulated BSTR is a NULL string.
Compares two _bstr_t objects.
Extract the pointers to the encapsulated Unicode or multibyte BSTR object.
