capability dependent

[bsteeb@gmx.de]

Hi,
could anybode explain what this mean in general.Sorry I could not find a clear statement in this forum.
1. am I wright that this is the backdoor for operators to individually protect their branded devices?
2.Do I really need capability all files,tcb.. to make shure that all api's work reliable on every device in worst case? - just for understanding.

thank you for your answer.

When you face "Capability: dependent" in the SDK Help, it means that the required capability depends on the arguments you pass to the given method.
For example general file access needs no capability. However if you want to have access to /sys, you need TCB capability, if you want to see the private folder of other applications you need AllFiles, etc.
So capabilities do not represent backdoors for operators, but the depth of their documentation varies a lot even in the same SDK Help page.
RSocket can be an example:

Open()
Capability: NetworkServices Required for opening 'udp' sockets. Conditional on parameter value KProtocolInetUdp
Capability: NetworkControl Required for opening 'icmp' sockets. Conditional on parameter value KProtocolInetIcmp
Capability: NetworkControl Required for opening 'icmp6' sockets. Conditional on parameter value KProtocolInet6Icmp
Capability: NetworkServices Required for opening 'tcp' sockets. Conditional on parameter value KProtocolInetTcp
Capability: NetworkControl Required for opening 'ip' sockets. Conditional on parameter value KProtocolInetIp
Capability: NetworkControl Required for opening 'ip6' sockets. Conditional on parameter value KProtocolInet6Ip
IMPORT_C TInt Open(RSocketServ &aServer, TUint addrFamily, TUint sockType, TUint protocol);

and

Open()
Capability: Dependent on the type of connection so deferred to PRT.
IMPORT_C TInt Open(RSocketServ &aServer, TUint addrFamily, TUint sockType, TUint protocol, RConnection &aConnection);

and these two methods are next to each other on the - obviously - same page.
