Detailed Description

Function Documentation

void ptp_MsgAnnounceRcv	(	ptp_octet *	pBuf,
		ptp_uinteger8	portNumber
	)

Receive Announce message.

This function acts when receive an Announce message from the network. IEC 61588-2009 / IEEE 1588-2008 Figure 29, section 9.5.3

Parameters

[in]	pBuf	Pointer to the data to parse
[in]	portNumber	Port number of receiver

(

)

Send Announce message.

This function sends an Announce message in broadcast mode. IEC 61588-2009 / IEEE 1588-2008 specifies one announce message per port, but it could be too costly for the device, so a broadcast model was adopted.

Returns

1 on success, 0 on fail.
