Why the return value will be greater than 0 when calling syscall(__NR_sched_getaffinity) in framework/delibs/dethread/unix/deThreadUnix.c

[innosilion]

I don't kown under what circumstances it will bu greater than 0.
this is not confirm to the calling habits of unix systems.

ret = syscall(_NR_sched_etaffinity,0,maskSize,&mask)
if (ret>0)
{
.....
}
