Function Documentation

void DetermineEndianess ( void )

Detects Endianess of the platform and sets global g_nOpENerPlatformEndianess variable accordingly.

Identify if we are running on a big or little endian system and set variable.

Detects Endianess of the platform and sets global variable g_nOpENerPlatformEndianess accordingly, whereas 0 equals little endian and 1 equals big endian

int EncapsulateIpAddress	(	EipUint16	port,
		EipUint32	address,
		EipByte **	communication_buffer
	)

Encapsulate the sockaddr information as necessary for the Common Packet Format data items.

Converts and adds the provided port and IP address into an common packet format message

Parameters

port	Port of the socket, has to be provided in big-endian
address	IP address of the socket, has to be provided in big-endian
communication_buffer	The message buffer for sending the message
