Function Documentation

void* NETIO_Packet_get_head

(

const NETIO_Packet_T *const

packet

)

Get a pointer to the current head.

Get a pointer to the current head. Note that it can be assumed that the payload buffer is contiguous.

Parameters:

[in]

packet

Packet to get the head pointer for

Returns:

pointer to packet head

MT Safety:

This operation is not thread safe.

RTI_BOOL NETIO_Packet_set_payload	(	NETIO_Packet_T *const	packet,
		void *	buffer,
		RTI_INT32	buffer_length
	)

Initialize a packet with a payload.

Parameters:

[in]	packet	Packet to initialize
[in]	buffer	Payload to initialize packet with
[in]	buffer_length	Length of the payload in bytes

Returns:

RTI_TRUE on success, RTI_FALSE on failure

MT Safety:

This operation is not thread safe.

RTI_SIZE_T NETIO_Packet_get_payload_length

(

const NETIO_Packet_T *const

packet

)

Get the length the packet payload.

Parameters:

[in]

packet

Packet to return the payload length for

Returns:

Length of payload, 0xffffffff if the length is invalid.

MT Safety:

This operation is not thread safe.
