FreeCredentialsHandle function (sspi.h)

  • Article

The FreeCredentialsHandle function notifies the security system that the credentials are no longer needed. An application calls this function to free the credential handle acquired in the call to the AcquireCredentialsHandle (General) function after calling the DeleteSecurityContext function to free any context handles associated with the credential. When all references to this credential set have been removed, the credentials themselves can be removed.

Failure to free credentials handles will result in memory leaks.
