This interface supplies ports to the session debug manager (SDM).

Syntax

IDebugPortSupplier2 : IUnknown

Notes for Implementers

A custom port supplier implements this interface to represent a port supplier.

Notes for Callers

A call to CoCreateInstance with a port supplier's GUID returns this interface (this is the typical way to obtain this interface). For example:

IDebugPortSupplier2 *GetPortSupplier(GUID *pPortSupplierGuid)
{
    IDebugPortSupplier2 *pPS = NULL;
    if (pPortSupplierGuid != NULL) {
        CComPtr<IDebugPortSupplier2> spPortSupplier;
        spPortSupplier.CoCreateInstance(*pPortSupplierGuid);
        if (spPortSupplier != NULL) {
            pPS = spPortSupplier.Detach();
        }
    }
    return (pPS);
}

A call to GetPortSupplier returns this interface, representing the current port supplier being used by Visual Studio.

GetPortSupplier returns this interface, representing the port supplier that created the port.
IEnumDebugPortSuppliers2 represents a list of IDebugPortSupplier interfaces (the IEnumDebugPortSuppliers interface is obtained from EnumPortSuppliers, representing all of the port suppliers registered with Visual Studio).

A debug engine typically does not interact with a port supplier.

Methods in Vtable Order

The following table shows the methods of IDebugPortSupplier2.

Method	Description
GetPortSupplierName	Gets the port supplier name.
GetPortSupplierId	Gets the port supplier identifier.
GetPort	Gets a port from a port supplier.
EnumPorts	Enumerates the ports that already exist.
CanAddPort	Verifies that a port supplier supports adding new ports.
AddPort	Adds a port.
RemovePort	Removes a port.

Remarks

A port supplier can identify itself by name and ID, add and remove ports, and enumerate all ports that the port supplier provides.
