Hi everyone,
My packet has the following format:
lower-layer header | my header | payload
There exists a nx_union filed in the header, thus the header length is not
fixed and the typical implementation of Packet.getPayload() may not work:
command void* Packet.getPayload(message_t* msg, uint8_t len) {
uint8_t* payload = call SubPacket.getPayload(msg, len +
sizeof(data_header_t));
if (payload != NULL) {
payload += sizeof(data_header_t);
}
return payload;
}
Can anyone give me some suggestion on how Packet.getPayload() can be
implemented on variable length header? Thanks.
