New field in all commands that send/receive profile introspection data
(PA_COMMAND_GET_CARD_INFO)
@ -351,6 +351,35 @@ New field in all commands that send/receive profile introspection data
The field is added once for every profile.
New client->server commands:
GET_NODE_INFO
GET_NODE_INFO_LIST
GET_NODE_INFO parameters:
uint32_t index
string name
When getting the node info by index, the index parameter must not be
PA_INVALID_INDEX and the name parameter must be NULL.
When getting the node info by name, the index parameter must be
PA_INVALID_INDEX and the name parameter must not be NULL or an empty string.
GET_NODE_INFO_LIST doesn't have parameters.
GET_NODE_INFO reply parameters:
uint32_t index
string name
string description
pa_direction_t direction
The index must not be PA_INVALID_INDEX. The name must not be NULL or empty. The
description must not be NULL or empty. The direction must be either OUTPUT or
INPUT, not both.
GET_NODE_INFO_LIST reply parameters are otherwise the same as with
GET_NODE_INFO, but the parameter list is repeated for each node.
#### If you just changed the protocol, read this
## module-tunnel depends on the sink/source/sink-input/source-input protocol
## internals, so if you changed these, you might have broken module-tunnel.
