int hwloc_shmem_topology_adopt(hwloc_topology_t *topologyp, int fd, hwloc_uint64_t fileoffset, void *mmap_address, size_t length, unsigned long flags)
Adopt a shared memory topology stored in a file.
int hwloc_shmem_topology_write(hwloc_topology_t topology, int fd, hwloc_uint64_t fileoffset, void *mmap_address, size_t length, unsigned long flags)
Duplicate a topology to a shared memory file.
int hwloc_shmem_topology_get_length(hwloc_topology_t topology, size_t *lengthp, unsigned long flags)
Get the required shared memory length for storing a topology.
