Define Documentation

#define fip_packet_getFromIP6Hdr_destAddr ( x ) fip_packet_getFromIPBuf_Uint8Unaligned(x + 24)

Get a single byte from the IPv6 Destination Address.

Parameters:

x

Offset of the byte to get.

Referenced by fip_isDestUnspecified(), and fip_sixlowpanhc_compress().

#define fip_packet_getFromIP6Hdr_destPtr ( ) (fip_packet_getIPBufPtr() + 24)

Get a pointer to the IPv6 Destination Address.

WARNING: If you change the IP address with this function, you need to reset the associated flags. It is better to use the fip_packet_copyToIP6Hdr_destAddr() function.
