Before I commit, how's this text? (extrapolate for the other functions) /** \brief Query the default memory binding policy and locality of the * current process or thread (the locality is returned in \p nodeset). * * If neither HWLOC_MEMBIND_PROCESS nor HWLOC_MEMBIND_THREAD is * specified, the current process is assumed to be single-threaded. * This is the most portable form as it permits hwloc to use either * process-based OS functions or thread-based OS functions, depending * on which are available. * * If HWLOC_MEMBIND_STRICT is specified, the process' (or thread's) * pages are first checked to see if they all have the same memory * binding policy. If they do not, -1 is returned and errno is set to * EXDEV. * * \note HWLOC_MEMBIND_STRICT is only supported with this function on * some systems. If it is specified on an unsupported system, -1 is * returned and errno is set to ENOSYS. * * If HWLOC_MEMBIND_STRICT is not specified, or if all the process' * (or thread's) pages have the same memory binding policy, \p nodeset * is cleared. Each page is then examined and has the bit set in \p * nodeset corresponding to the NUMA node where it is located. The * resulting \p nodeset represents the set of NUMA nodes containing * all the pages in the process (or thread). * * If any other flags are specified, -1 is returned and errno is set * to EINVAL. */ HWLOC_DECLSPEC int hwloc_get_membind_nodeset(hwloc_topology_t topology, hwloc_nodeset_t nodeset, hwloc_membind_policy_t * policy, int flags); -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
