The same protocol can be installed on many handles in
the handle database.  For example, if there are multiple
mass storage devices in a platform, there will be
multiple Block I/O Protocols in the handle database.

[edk2] OpenProtocolInformation

2018-10-23 Thread TVKR 
Hi,

If the main purpose of the OpenProtocolInformation service is to provide
the complete list of agents currently using a specific protocol interface
then what is the need for providing the Handle argument too as an input?
Why does it matter what Handle was this queried protocol installed on?

Thanks
