WWSAPI Populating the (soapenv:Header) when the generated function only fills in the body.

Question

I'm trying to connect to a web service from a C++ app using WWSAPI.  I got the base connection working just fine.  My SOAP message has two parts though, a SOAPHeader (soapenv:Header) and a body (soapenv:Body).  the generated functions only fill in the body.  How do I set the Header information?  I am using WsAddCustomHeader to populate a message with the struct that contains the header data but I don't know what to do with this message as it is not a parameter in the generated function.

 

The generated wsdl.h file specifies the soap header and the function call:

//  input message soap header element is

//(WS_ELEMENT_DESCRIPTION*)&SOAPHeaderType_xsd.globalElements.auditInfo,

// operation: ICBC_Admin_whoAmI_Binder__whoAmI

HRESULT WINAPI ICBC_Admin_whoAmI_Binder__whoAmI(
