rgdispidNamedArgs
rgdispidNamedArgs is a field used with the COM IDispatch interface, specifically within the DISPPARAMS structure that governs late-bound method invocation. It is a pointer to an array of DISPIDs that identify which of the provided arguments are named arguments. The array length is given by cNamedArgs, and the total number of arguments is given by cArgs. The rgvarg array holds the actual argument values and is organized in reverse order (the last argument is at index 0).
During an invocation, the named arguments are identified by the DISPID values in rgdispidNamedArgs. The i-th
This mechanism is commonly used in languages that host COM objects and support named parameters, enabling more
In summary, rgdispidNamedArgs identifies which arguments are named and provides their DISPIDs, while rgvarg holds the
