StrRetToStrW function (shlwapi.h)

  • Άρθρο

Takes an STRRET structure returned by IShellFolder::GetDisplayNameOf and returns a pointer to an allocated string containing the display name.

Syntax

LWSTDAPI StrRetToStrW(
  [in, out]      STRRET          *pstr,
  [in, optional] PCUITEMID_CHILD pidl,
  [out]          LPWSTR          *ppsz
);

Parameters

[in, out] pstr

Type: STRRET*

A pointer to the STRRET structure. When the function returns, this pointer will no longer be valid.

[in, optional] pidl

Type: PCUITEMID_CHILD

A pointer to the item's ITEMIDLIST structure. This value can be NULL.

[out] ppsz

Type: LPTSTR*

A pointer to an allocated string containing the result. StrRetToStr allocates memory for this string with CoTaskMemAlloc. You should free the string with CoTaskMemFree when it is no longer needed.

Return value

Type: HRESULT

If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

Note

The shlwapi.h header defines StrRetToStr as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
