#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_gateway_network_command(
    network: *mut PamojaGatewayNetwork,
    dev_addr: u32,
    slot: PamojaGatewayNetworkSlot,
    commands: *const PamojaLorawanMacCommand,
    commands_len: usize,
    buffer: *mut u8,
    capacity: usize,
    out_txpk: *mut PamojaGatewayTxpk,
    out_len: *mut usize,
) -> PamojaStatus

Builds a downlink carrying MAC commands, which is how a network configures a relay.

The commands ride in the frame options where they fit, and in a frame of their own on port 0 where they do not.

Arguments

• network - the network.
• dev_addr - the device to configure.
• slot - where and when to transmit, from the event that reported its uplink.
• commands - the commands to send.
• commands_len - how many there are.
• buffer - where to write the frame to transmit.
• capacity - how many bytes the buffer holds.
• out_txpk - receives the packet that carries it.
• out_len - receives how many bytes were written.

Returns

PamojaStatus::Ok, PamojaStatus::InvalidArgument for a null argument, a command the boundary cannot read, or a buffer too small, or PamojaStatus::Codec when no session is held for the address.

Safety

network must be a live handle, commands must point at commands_len readable commands, buffer must point at capacity writable bytes or be null, and both outputs must be writable.
