Syntax

CRYPTCATATTRIBUTE * CryptCATPutCatAttrInfo(
  [in] HANDLE hCatalog,
  [in] LPWSTR pwszReferenceTag,
  [in] DWORD  dwAttrTypeAndAction,
  [in] DWORD  cbData,
  [in] BYTE   *pbData
);

Parameters

[in] hCatalog

A handle to the catalog obtained from the CryptCATOpen or CryptCATHandleFromStore functions.

[in] pwszReferenceTag

A pointer to a null-terminated string for the name of the attribute.

[in] dwAttrTypeAndAction

A value that represents a bitwise combination of the following flags. The caller must at least specify CRYPTCAT_ATTR_DATAASCII or CRYPTCAT_ATTR_DATABASE64.

0x10000000
 The attribute is authenticated.
CRYPTCAT_ATTR_UNAUTHENTICATED
0x20000000

[in] cbData

A value that specifies the number of bytes in the pbData buffer.

[in] pbData

A pointer to a memory buffer that contains the attribute value.

Return value
