/**
* wp_endpoint_create_link:
* @self: the endpoint
* @props: the link properties
*
* Creates a #WpEndpointLink between @self and another endpoint, which
* must be specified in @props.
* @props may contain:
* - `endpoint-link.output.endpoint`: the bound id of the endpoint
* that is in the %WP_DIRECTION_OUTPUT direction
* - `endpoint-link.output.stream`: the bound id of the endpoint stream
* that is in the %WP_DIRECTION_OUTPUT direction
* - `endpoint-link.input.endpoint`: the bound id of the endpoint
* that is in the %WP_DIRECTION_INPUT direction
* - `endpoint-link.input.stream`: the bound id of the endpoint stream
* that is in the %WP_DIRECTION_INPUT direction
*
* If either stream id are not specified (or set to -1), then the first
* available stream of this endpoint is used for the link.
*
* The id of @self is not necessary to be specified, so only one of
* `endpoint-link.output.endpoint`, `endpoint-link.input.endpoint`
* is actually required.
