Member Typedef Documentation

Event

using SNMP::SNMP::Event = void (*)(const Message*, const IPAddress, const uint16_t)

private

On message event user handler type.

The sketch must define an event handler function to process incoming message.

Example

void onMessage(const SNMP::Message *message, const IPAddress remote, const uint16_t port) {
    // User code here...
}

Parameters

message	SNMP message to process.
remote	IP address of the sender.
port	UDP port of the sender.

Constructor & Destructor Documentation

SNMP()

SNMP::SNMP::SNMP ( const uint16_t port )

inlineprivate

Creates an SNMP object.

Parameters

port

UDP port.

Definition at line 137 of file SNMP.h.

Member Function Documentation

begin()

bool SNMP::SNMP::begin ( UDP & udp )

inline

Initializes network.

Parameters

udp	UDP client.

Returns

1 if success, 0 if failure.

Definition at line 59 of file SNMP.h.

loop()

void SNMP::SNMP::loop ( )

inline

Network read operation.

Read incoming packet, parses as an SNMP message an calls user message handler.

Warning

This function must be called frequently from the sketch loop() function.

Definition at line 72 of file SNMP.h.

onMessage()

void SNMP::SNMP::onMessage ( Event event )

inline

Sets on message event user handler.

Parameters

event

Event handler.

Definition at line 127 of file SNMP.h.

send()

bool SNMP::SNMP::send ( Message * message, const IPAddress ip, const uint16_t port )

inline

Network write operation.

Builds message and write outgoing packet.

Parameters

message	SNMP message to send.
ip	IP address to send to.
port	UDP port to send to

Returns

1 if success, 0 if failure.
