Loads a string that contains each of the characters that are valid or invalid in the namespace under which it is called.
Type: LPWSTR*
A pointer to a string that contains all valid characters in the namespace. If the namespace provides any invalid characters in ppwszInvalidChars, then this value returns NULL. See Remarks for more details.
Type: LPWSTR*
A pointer to a string that contains all invalid characters in the namespace.
Type: HRESULT
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
As an example, the standard file system returns the string "/:*?"<>|" in ppwszInvalidChars and NULL in ppwszValidChars.
Both parameters cannot return non-NULL values, so ppwszValidChars is assigned a value of NULL because of the non-NULL value
in ppwszInvalidChars. It is assumed that when there are specified invalid characters, everything else is valid. Only when ppwszInvalidChars is NULL does ppwszValidChars contain a list of all valid characters.
If the method returns a success code, the allocated string must be freed using CoTaskMemFree.
