CigiIGUserDefined Class


void setPacketID ( int id ) #

Sets the ID of the user-defined packet.


  • int id - ID of the user-defined packet.

void setData ( const unsigned char * data, int size ) #

Sets the user-defined data.
Bytes are read and written starting from the 2nd byte (not from the 4th). If you want to align bytes starting from the 4th one, you should add a couple of bytes in the beginning. The CIGI ICD recommends to start reading/writing bytes starting from the 4th one (see Data before the Data Block 1 shown in the images below), although it is mentioned, that it is possible to start from the 2nd.

General User-Defined Packet Structure


  • const unsigned char * data - User-defined data.
  • int size - Size of the packet.
