The WinTrustProviderClientUnload function indicates that WinTrust is preparing to unload the trust provider DLL from the client application. However, WinTrust does not guarantee that it will call this function before the client process exits. Therefore, the trust provider should use other cleanup mechanisms, if necessary.
VOID WinTrustProviderClientUnload(
LPVOID lpTrustProviderInfo |
// pointer to buffer allocated by the trust provider |
); |
None.
The LPWINTRUST_PROVIDER_CLIENT_UNLOAD type is a pointer to a WinTrustProviderClientUnload function.
