Source 
#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_loopback_transport_recv(
    transport: *mut PamojaLoopbackTransport,
    out_message: *mut *mut PamojaMessage,
) -> PamojaStatus
Expand description

Waits for the next message on a subscribed topic.

§Arguments

  • transport - the link.
  • out_message - receives a message handle, or null when the link is closed.

§Returns

PamojaStatus::Ok on success. A null out_message with an Ok status means the link closed rather than that anything failed.

§Safety

transport must be a live handle and out_message must be writable.
