Returns a list of provider-specific keywords.
HRESULT GetKeywords(
LPOLESTR * ppwszKeywords);
Parameters
ppwszKeywords
[out]
A pointer to memory in which to return the address of a string. The string contains a comma-separated list of all keywords unique to this provider; that is, a comma-separated list of keywords that are not in the list in the Comments section. If there are no keywords unique to this provider, or if an error occurs, the provider sets *ppwszKeywords to a null pointer.
The provider allocates memory for the string and returns the address to this memory; the consumer releases this memory with IMalloc::Free when it no longer needs the string.

E_OUTOFMEMORY
