Hashes a URL string.
Type: PCTSTR
A null-terminated string of maximum length INTERNET_MAX_URL_LENGTH that contains the URL.
Type: BYTE*
A pointer to a buffer that, when this function returns successfully, receives the hashed array.
Type: DWORD
The number of elements in the array at pbHash. It should be no larger than 256.
Type: HRESULT
If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
To hash a URL into a single byte, set cbHash = sizeof(BYTE) and pbHash = (LPBYTE)&bHashedValue, where bHashedValue is a one-byte buffer. To hash a URL into a DWORD, set cbHash = sizeof(DWORD) and pbHash = (LPBYTE)&dwHashedValue, where dwHashedValue is a DWORD buffer.
Note
The shlwapi.h header defines UrlHash 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.
