[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The GetName method retrieves the name of a profile.

Syntax

HRESULT GetName(
  [out]     WCHAR *pwszName,
  [in, out] DWORD *pcchName
);

Parameters

[out] pwszName

Pointer to a wide-character null-terminated string containing the name. Pass NULL to retrieve the length of the name.

[in, out] pcchName

On input, specifies the length of the pwszName buffer. On output, if the method succeeds, specifies a pointer to the length of the name, including the terminating null character.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code	Description
S_OK	The method succeeded.
E_INVALIDARG	The pcchName parameter is NULL.
ASF_E_BUFFERTOOSMALL	The pwszName parameter is not large enough.
E_UNEXPECTED	The method failed for an unspecified reason.

Remarks

You should make two calls to GetName. On the first call, pass NULL as pwszName. On return, the value pointed to by pcchName is set to the number of wide characters, including the terminating null character, required to hold the profile name. Then you can allocate the required amount of memory for the string and pass a pointer to it as pwszName on the second call.

Profiles have names and descriptions that are used when displaying lists of profiles.
