Subject: [PATCH V2 3/9] MdeModulePkg/Variable: Parameterize VARIABLE_INFO_ENTRY buffer
Date: Fri, 27 Sep 2019 18:47:11 -0700 [thread overview]
Message-ID: <20190928014717.31372-4-michael.a.kubacki@intel.com> (raw)
In-Reply-To: <20190928014717.31372-1-michael.a.kubacki@intel.com>
UpdateVariableInfo () currently accepts parameters regarding updates
to be made to a global variable of type VARIABLE_INFO_ENTRY. This
change passes the structure by pointer to UpdateVariableInfo ()
so structures can be updated outside the fixed global variable.
