michele lattuada

Hello,
I would like to use a mailbox and i've studied the RTX manual. But i still have a problem.. I want to use the message of the mailbox in a switch, but i cannot understand what i should pass to the switch.

Here is the part of the code:

void* msg;

        while(1) {


        os_mbx_wait(MsgBox,&msg,0xffff);

                switch (*msg){
                        case button_right :
                                counter +=2;
                                break;
                        case button_up:
                                counter ++;
                                break;
                        case button_down:
                                counter --;
                                break;
                        case button_left:
                                counter -=2;
                                break;
                        case button_select:
                                break;

And the error i receive is:

tisifone_task_2b.c(73): error:  #31: expression must have integral type
tisifone_task_2b.c:             switch (*msg){


The message came from another task which send a pointer to an int.

How can i work with a message coming from a mailbox?? Many thanks.
