SHRegEnumUSValue function

Enumerates the values of the specified registry subkey in a user-specific subtree (HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE).

Syntax


LSTATUS SHRegEnumUSValue(
  _In_         HUSKEY hUSKey,
  _In_         DWORD dwIndex,
  _Out_        LPTSTR pszValueName,
  _Inout_      LPDWORD pcchValueNameLen,
  _Out_opt_    LPDWORD pdwType,
  _Out_opt_    void *pvData,
  _Inout_opt_  LPDWORD pcbData,
  _In_         SHREGENUM_FLAGS enumRegFlags
);

Parameters

hUSKey [in]

Type: HUSKEY

A handle to a currently open registry subkey. The subkey must have been opened with the KEY_SET_VALUE access right. For more information, see Registry Key Security and Access Rights.

This handle can be obtained through the SHRegOpenUSKey function.

dwIndex [in]

Type: DWORD

The index of the value to retrieve. This parameter should be zero for the first call and incremented for subsequent calls.

pszValueName [out]

Type: LPTSTR

A pointer to a character buffer that receives the enumerated value name. The size of this buffer is specified in pcchValueNameLen.

pcchValueNameLen [in, out]

Type: LPDWORD

A pointer to a DWORD that, on entry, contains the size of the buffer at pszValueName, in characters. On exit, this contains the number of characters that were copied to pszValueName.

pdwType [out, optional]

Type: LPDWORD

A pointer to a DWORD that receives the data type of the value. These are the same values as those described under the lpType parameter of RegEnumValue.

pvData [out, optional]

Type: void*

A pointer to a buffer that receives the data for the value entry. The size of this buffer is specified in pcbData. This parameter can be NULL if the data is not required.

pcbData [in, out, optional]

Type: LPDWORD

A pointer to a DWORD that, on entry, contains the size of the buffer at pvData. On exit, this contains the number of bytes that were copied to pvData.

enumRegFlags [in]

Type: SHREGENUM_FLAGS

One of the SHREGENUM_FLAGS that specifies the base key in which the enumeration should take place.

Return value

Type: LSTATUS

Returns ERROR_SUCCESS if successful, or a nonzero error code defined in Winerror.h otherwise. You can use the FormatMessage function with the FORMAT_MESSAGE_FROM_SYSTEM flag to retrieve a textual description of the error.
