[The CryptCATEnumerateAttr function is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions.]

The CryptCATEnumerateAttr function enumerates the attributes associated with a member of a catalog. This function has no associated import library. You must use the LoadLibrary and GetProcAddress functions to dynamically link to Wintrust.dll.

A pointer to the CRYPTCATMEMBER structure that identifies which member of the catalog is being enumerated.

[in] pPrevAttr

A pointer to the previously returned value from this function or pointer to NULL to start the enumeration.

Return value

The return value is a pointer to the CRYPTCATATTRIBUTE structure that contains the attribute information or NULL, if no more attributes are in the enumeration or if an error is encountered. The returned pointer is passed in as the pPrevAttr parameter for subsequent calls to this function.
