Function Documentation

ping()

error_t ping	(	NetInterface *	interface,
		const IpAddr *	targetIpAddr,
		size_t	size,
		uint8_t	ttl,
		systime_t	timeout,
		systime_t *	rtt
	)

Test the reachability of a host.

Ping operates by sending an ICMP Echo Request message to the target host and waiting for an ICMP Echo Reply message

Parameters

[in]	interface	Underlying network interface (optional parameter)
[in]	targetIpAddr	IP address of the host to reach
[in]	size	Size of the data payload in bytes
[in]	ttl	Time-To-Live value to be used
[in]	timeout	Maximum time to wait before giving up
[out]	rtt	Round-trip time (optional parameter)

Returns

Error code

Definition at line 69 of file ping.c.

pingBindToInterface()

error_t pingBindToInterface	(	PingContext *	context,
		NetInterface *	interface
	)

Select a particular network interface.

Parameters

[in]	context	Pointer to the ping context
[in]	interface	Network interface to be used

Returns

Error code

Definition at line 167 of file ping.c.

pingInit()

void pingInit

(

PingContext *

context

)

Initialize ping context.

Parameters

[in]

context

Definition at line 125 of file ping.c.

pingRelease()

void pingRelease

(

PingContext *

context

)

Release ping context.

Parameters

[in]

context

Pointer to the ping context

Definition at line 558 of file ping.c.

pingSendRequest()

error_t pingSendRequest	(	PingContext *	context,
		const IpAddr *	targetIpAddr,
		size_t	size,
		uint8_t	ttl
	)

Send an ICMP Echo Request message.

Parameters

[in]	context	Pointer to the ping context
[in]	targetIpAddr	IP address of the host to reach
[in]	size	Size of the data payload, in bytes
[in]	ttl	Time-To-Live value to be used

Returns

Error code

Definition at line 190 of file ping.c.

pingSetTimeout()

error_t pingSetTimeout	(	PingContext *	context,
		systime_t	timeout
	)

Set timeout value.

Parameters

[in]	context	Pointer to the ping context
[in]	timeout	Maximum time to wait

Returns

Error code

Definition at line 146 of file ping.c.

pingWaitForReply()

error_t pingWaitForReply	(	PingContext *	context,
		IpAddr *	targetIpAddr,
		systime_t *	rtt
	)

Wait for a matching ICMP Echo Reply message.

Parameters

[in]	context	Pointer to the ping context
[out]	targetIpAddr	IP address of the remote host (optional parameter)
[out]	rtt	Round-trip time (optional parameter)

Returns

Error code
