SHRegEnumUSKey function

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

Syntax


LSTATUS SHRegEnumUSKey(
  _In_    HUSKEY          hUSKey,
  _In_    DWORD           dwIndex,
  _Out_   LPTSTR          pszName,
  _Inout_ LPDWORD         pcchName,
  _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 subkey to retrieve. This parameter should be zero for the first call and incremented for subsequent calls.

pszName [out]

Type: LPTSTR

A pointer to a character buffer that receives the enumerated key name.

pcchName [in, out]

Type: LPDWORD

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

enumRegFlags [in]

Type: SHREGENUM_FLAGS

A 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.
