◆ interface()
Get the protocol number that must be used for the interface with the number idx.
- Parameters
-
| idx | The index of the interface to get the protocol number for. idx must be >= 0 and < the return value of num_interfaces(). |
| [out] | proto | The protocol number for interface idx. |
| [out] | name | The protocol name for interface idx. |
- Return values
-
| l4_msgtag_t::label() == 0 | Successful; see `proto` and `name`. |
| l4_msgtag_t::label() < 0 | Error code. |
◆ num_interfaces()
Get the number of interfaces implemented by this object.
- Return values
-
| l4_msgtag_t::label() >= 0 | The number of supported interfaces. |
| l4_msgtag_t::label() < 0 | Error code of the occurred error. |
◆ supports()
Figure out if the object supports the given protocol (number).
- Parameters
-
| protocol | The protocol number to check for. |
- Return values
-
| l4_msgtag_t::label() == 1 | protocol is supported. |
| l4_msgtag_t::label() == 0 | protocol is not supported. |
This method is intended to be used for statically assigned protocol numbers.
