Function Documentation

static __inline__ void topo_cpuset_from_linux_libnuma_ulongs ( topo_topology_t  topology,
topo_cpuset_t cpuset,
const unsigned long *  mask,
unsigned long  maxnode 
) [static]

Convert the array of unsigned long mask into libtopology CPU set cpuset.

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).

static __inline__ void topo_cpuset_to_linux_libnuma_ulongs ( topo_topology_t  topology,
const topo_cpuset_t cpuset,
unsigned long *  mask,
unsigned long *  maxnode 
) [static]

Convert libtopology 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.
