Hi Paul,
I think that you must check the return value of the call that you make to
"setsockopt()", especially for the second call. The first one returns 0,
this is, the "setsockopt()" call was executed correctly. However, the second
one returns -16 ("EBUSY" value), this is, the call to "setsockopt()" was not
executed correctly.
So, could you modify your calls to "setsockopt()" and check whether the
return value is 0 (correct execution) or -16 (EBUSY, incorrect execution)?
Best, Cardo.
