IWMMutualExclusion2::GetName method (wmsdkidl.h)

[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 It has been superseded by Source Reader and Sink Writer.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 the current mutual exclusion object. A mutual exclusion object has a name only if a name has been assigned using the IWMMutualExclusion2::SetName method.

Syntax

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

Parameters

[out] pwszName

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

[in, out] pcchName

On input, a pointer to a variable containing the length of the pwszName array in wide characters (2 bytes). On output, if the method succeeds, the variable contains 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.

Remarks

You can pass pwszName as NULL to retrieve the correct size of the name in pcchName and then make another call to this method with a properly sized string. If you do, the value you pass as pcchName is irrelevant. It will be replaced with the correct length of the name.

If you pass an address as pwszName, and the length you specified in pcchName is shorter than the number of characters required to store the name, GetName ignores pwszName and returns the correct number of characters in pcchName. In this case the method still returns S_OK.
