3.1.4.2.14 ICertAdminD2::GetConfigEntry (Opnum 44)

  • Artículo

The GetConfigEntry method retrieves the CAs that persisted the configuration data listed in section 3.1.1.10. Configuration data is represented as a hierarchical data structure with the following format: [\pwszAuthority][\pwszNodePath][\pwszEntry].

 HRESULT GetConfigEntry(
   [in, string, unique] wchar_t const* pwszAuthority,
   [in, string, unique] wchar_t const* pwszNodePath,
   [in, string, ref] wchar_t const* pwszEntry,
   [out, ref] VARIANT* pVariant
 );

pwszAuthority: See the pwszAuthority definition in section 3.1.4.1.1.

pwszNodePath: A string value that represents the node path for the configuration information. This parameter can be an empty string and MUST NOT be NULL.<72>

pwszEntry: A string value that represents the name of the leaf entry whose information is being retrieved. This value can be an EMPTY string and MUST NOT be NULL.<73>

pVariant: A pointer to a VARIANT that receives the requested information.

On Windows, the CA uses these datatypes to set the data that it stores in the registry:

REG_BINARY – The vt member of VARIANT is set to VT_ARRAY|VT_UI1 and the pArray member references a single dimension SAFEARRAY the binary data. The number of elements of the SAFEARRAY reference by pArray is equal to the length of binary data.

REG_DWORD – The vt member of VARIANT is set to VT_I4 and the lVal member is the registry value.

REG_SZ – The vt member of VARIANT is set to VT_BSTR and the bstrVal member is set to BSTR for Unicode string in the registry value.

REG_MULTI_SZ – The vt member of VARIANT is set to VT_ARRAY|VT_BSTR and the pArray member references a single dimension SAFEARRAY. The number of elements of the SAFEARRAY referenced by pArray is equal to the number of the strings in the registry value. For each string, there is an element in the SAFEARRAY referenced by pArray containing the BSTR for Unicode string value in the registry.

The GetConfigEntry method retrieves the CA configuration data or configuration data hierarchy information.

The following processing rules apply:

  1. If pwszAuthority parameter is EMPTY and pwszNodePath parameter is EMPTY and pwszNodeEntry is EMPTY, the CA MUST return all available leaf properties' names that exist in the configuration's root node as a VARIANT array.

  2. If pwszAuthority is EMPTY and pwszNodePath is EMPTY and pwszNodeEntry is not EMPTY, the CA must return the leaf property value identified by pwszNodeEntry that exists under the Configuration root node as a VARIANT.

  3. If pwszAuthority is EMPTY and pwszNodePath is not EMPTY, for any value of pwszNodeEntry the CA MUST fail the call with an error code of 0x80070057.

  4. If pwszAuthority parameter is not EMPTY and pwszNodePath is EMPTY and pwszNodeEntry is EMPTY, the CA MUST return all available leaf properties' names that exist under the pwszAuthority node as a VARIANT array.

  5. If pwszAuthority parameter is not EMPTY and pwszNodePath is EMPTY and pwszNodeEntry is not EMPTY, the CA MUST return the leaf property value identified by pwszNodeEntry that exists under the pwszAuthority node as a VARIANT array.

  6. If pwszAuthority parameter is not EMPTY and pwszNodePath is not EMPTY and pwszEntry is EMPTY, the CA MUST return all available leaf properties' names that exist under the pwszNodePath node as a VARIANT array.

  7. If pwszAuthority parameter is not EMPTY and pwszNodePath is not EMPTY and pwszEntry is not EMPTY, the CA MUST return the leaf property value identified by pwszNodeEntry that exists under the pwszNodePath node as a VARIANT array.

  8. For each input in the left column of the table below, the CA MUST perform the processing rules in the corresponding cell in the right column.
