Subject: [9fans] Unexpected 8c warning message
Date: Sun,  9 Aug 2009 21:33:02 +0200	[thread overview]
Message-ID: <4A7F246E.8000504@tecmav.com> (raw)

Hi, all.

SDes_t  *SDList[2], *SD;
....
n = ...       //  0, 1, 2, ...

//SD = SDList[0];         <= uncommenting this one the warning disappear.

for (i = 0;  i < 2;  i++)
{
       SD = SDList[i];
       while (n && SD)
       {
             SD = SD->next;
             if (SD) n--;
       }
}

if (!SD) {  ..... }    ---> used and not set SD ???

8c shouldn't issue the warning message, beeing SD assigned in a loop
defined by constants ... unless there is a subtle (my) error that I
don't see.

Thanks for the help.

adriano
