UrlCreateFromPathW function (shlwapi.h)

Converts a Microsoft MS-DOS path to a canonicalized URL.

Syntax

LWSTDAPI UrlCreateFromPathW(
  [in]      PCWSTR pszPath,
  [out]     PWSTR  pszUrl,
  [in, out] DWORD  *pcchUrl,
            DWORD  dwFlags
);

Parameters

[in] pszPath

Type: PCTSTR

A null-terminated string of maximum length INTERNET_MAX_URL_LENGTH that contains the MS-DOS path.

[out] pszUrl

Type: PTSTR

A pointer to a buffer that, when this function returns successfully, receives the URL.

[in, out] pcchUrl

Type: DWORD*

The number of characters in pszUrl.

dwFlags

Type: DWORD

Reserved. Set this parameter to NULL.

Return value

Type: HRESULT

Returns S_FALSE if pszPath is already in URL format. In this case, pszPath will simply be copied to pszUrl. Otherwise, it returns S_OK if successful or a standard COM error value if not.

Remarks

Note  UrlCreateFromPath does not support extended paths. These are paths that include the extended-length path prefix "\\?\".

 

Note

The shlwapi.h header defines UrlCreateFromPath 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.
