IMDSPDevice::GetName method (mswmdm.h)

  • Article

The GetName method retrieves the name of the device.

Syntax

HRESULT GetName(
  [out] LPWSTR pwszName,
  [in]  UINT   nMaxChars
);

Parameters

[out] pwszName

Pointer to an array of 16-bit Unicode characters that receives the device name string.

[in] nMaxChars

Maximum number of characters to copy to the string.

Return value

The method returns an HRESULT. All the interface methods in Windows Media Device Manager can return any of the following classes of error codes:

  • Standard COM error codes
  • Windows error codes converted to HRESULT values
  • Windows Media Device Manager error codes
For an extensive list of possible error codes, see Error Codes.

Remarks

The LPWSTR string type is a 16-bit Unicode character string and does not accept byte-sized characters. To convert a string of byte-sized characters (LPCSTR) to an LPWSTR string, use the MultiByteToWideChar function as described in Microsoft Windows documentation.

Device names must not contain trailing spaces.

This method must be implemented. It must not return WMDM_E_NOTSUPPORTED or E_NOTIMPL. For more information, see Mandatory and Optional Interfaces.
