Allows a security package to discontinue the impersonation of the caller and restore its own security context.

Syntax

KSECDDDECLSPEC SECURITY_STATUS SEC_ENTRY RevertSecurityContext(
  [in] PCtxtHandle phContext
);

Parameters

[in] phContext

Handle of the security context being impersonated. This handle must have been obtained in the call to the AcceptSecurityContext (General) function and used in the call to the ImpersonateSecurityContext function.

Return value

If the function succeeds, the return value is SEC_E_OK.

If the function fails, the return value can be one of the following error codes.

Return code	Description
SEC_E_INVALID_HANDLE	The handle passed to the function is not valid.
