pLWIAPROPERTIES is a pointer to an LWIAPROPERTIES structure. If the function parameter type is pLWIAPROPERTIES, declare an LWIAPROPERTIES variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pWIAPROPERTIES variable is necessary only for programs requiring a pointer.
