C: data problem in a struct

[alsig]

Hi,
I have an embedded system which runs FreeRTOS. I have several applications on top of FreeRTOS and one of them is a message parser. All messages that needs to be sent between the different application have to go through the message parser application.

My problem is the the data varies depending on the which applications communicates and i want to use the same message structure for all the applications. Sometimes the data are simple like chars and ints and other times the data is a struct.

    int sharedfield1[16];
    char sharedfield2[64];
  } context;
} msg;
