The function in question is:
/*****
Purpose: To increase/decrease the CW message index for the messages displayed at bottom of display.
Parameter list:
int direction was the UP or DN buatton pressed?
int index the current index into the CW message array
Return value:
int The new index into the array
CAUTION:
*****/
int ChangeSwitchIndex(int direction, int index)
{
// static int count = ELEMENTCOUNT(contestExchanges) - 1;
static int count = NUM_ELEMENTS(sizeof(contestExchanges), sizeof(contestExchanges[0])) - 1;
if (direction) {
index++;
if (index > count)
index = 1; // First element to use
} else {
index--;
if (index == 0) // First element used to erase
index = count;
}
return index;
}
and that code appears in the *.cpp file. I have your function placed in the header file, as I don't want to duplicate it in the other files. Indeed, I would expect it to draw an error if I did.
