Subject: [Cs-dev] syncgrain.c and MAXINT

John,

 

the change fin syncgrain.c from

 

p->count = 0xFFFFFFFF;

 

to

 

p->count = MAXINT;

 

seems to have introduced a bug in the code. Would you be able to suggest

a solution?

 

Victor

The problem is that 0xffffffff is negative on a 32bit machine but not
on 64bit.  I am sure old code is wrong but do not understand what is
happening.
  Will take another look

What do you want count to start as?

-1 (0xffffffff on 32bits)
a large number
any negative number?
UINT_MAX?
INT_MIN?

I changed the code so that count can be initialised to 0.
