Subject: [hwloc-users] Return value hwloc functions
From: Gabriele Fatigati (g.fatigati_at_[hidden])

Hi all,

in hwloc manual, return value of many functions in error case are:

-1 with errno set to ENOSYS if the action is not supported
-1 with errno set to EXDEV if the binding cannot be enforced

What's the difference?
