Convert the array of unsigned long mask
into hwloc CPU set.
mask
is a array of unsigned long that will be read. maxnode
contains the maximal node number that may be read in mask
.
This function may be used after calling get_mempolicy or any other function that takes an array of unsigned long as output parameter (and possibly a maximal node number as input parameter).

Convert hwloc CPU set cpuset
into the array of unsigned long mask
.
mask
is the array of unsigned long that will be filled. maxnode
contains the maximal node number that may be stored in mask
. maxnode
will be set to the maximal node number that was found, plus one.
This function may be used before calling set_mempolicy, mbind, migrate_pages or any other function that takes an array of unsigned long and a maximal node number as input parameter.
