Thread: Questions on behavior of code

I am having problem understanding the behavior of the code below, can somebody advise me on how the function behave and work?This is a function that suppose to add or drop data from a hardware device. Thanks.


bit OADM_AddDrop(void)
{
bit bDropOADS=0, bAddOADS=0;
int i=0, iPortValue=0, iPorts=pMsg[0], j=0;
//sbit SetBit;

if(iPorts>PORT_SWITCH_MAX) return false; //every call can only set up to 8 ports/mirrors

for(i=0; i<iPorts; i++)
{
iPortValue=pMsg[i+1];

if(iPortValue>0 && iPortValue<9) //from 1 to 64
{
//////////testing//////////////
ACC='K';
TX_BYTE();
ACC='K';
TX_BYTE();
ACC=iPortValue;
TX_BYTE();
ACC=pCardStatus[STATUS_DROP_BYTE];
TX_BYTE();
ACC='K';
TX_BYTE();
ACC='K';
TX_BYTE();
/////////////////////////////////

j=iPortValue-1;
if (j==0)
{SetBit10=pCardStatus[STATUS_DROP_BYTE]^0; SetBit10=1;}
if (j==1)
{SetBit11=pCardStatus[STATUS_DROP_BYTE]^1; SetBit11=1;}
if (j==2)
