SHRegEnumUSKey function
Applies to: desktop apps only
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.
