rsm_get_interconnect_topology(3RSM) Remote Shared Memory Library Functions rsm_get_interconnect_topology(3RSM) NAME
rsm_get_interconnect_topology, rsm_free_interconnect_topology - get or free interconnect topology SYNOPSIS
cc [ flag... ] file... -lrsm [ library... ] #include <rsmapi.h> int rsm_get_interconnect_topology(rsm_topology_t **topology_data); void rsm_free_interconnect_topology(rsm_topology_t *topology_data); DESCRIPTION
The rsm_get_interconnect_topology(3RSM) and rsm_free_interconnect_topology(3RSM) functions provide for access to the interconnect con- troller and connection data. The key interconnect data required for export and import operations includes the respective cluster nodeids and the controller names. To facilitate applications in the establishment of proper and efficient export and import policies, a delineation of the interconnect topology is provided by this interface. The data provided includes local nodeid, local controller name, its hardware address, and remote connection specification for each local controller. An application component exporting memory can thus find the set of existing local controllers and correctly assign controllers for the creation and publishing of segments. Exported segments may also be efficiently distributed over the set of controllers consistent with the hardware interconnect and application software. An application component which is to import memory must be informed of the segment id(s) and controller(s) used in the exporting of mem- ory, this needs to be done using some out-of-band mechanism. The topology data structures are defined in the <rsmapi.h> header. The rsm_get_interconnect_topology() returns a pointer to the topology data in a location specified by the topology_data argument. The rsm_free_interconnect_topology() frees the resources allocated by rsm_get_interconnect_topology(). RETURN VALUES
Upon successful completion, rsm_get_interconnect_topology() returns 0. Otherwise, an error value is returned to indicate the error. ERRORS
The rsm_get_interconnect_topology() function can return the following errors: RSMERR_BAD_TOPOLOGY_PTR Invalid topology pointer. RSMERR_INSUFFICIENT_MEM Insufficient memory. RSMERR_BAD_ADDR Bad address. ATTRIBUTES

rsm_memseg_import_connect(3RSM) Remote Shared Memory Library Functions rsm_memseg_import_connect(3RSM) NAME
rsm_memseg_import_connect, rsm_memseg_import_disconnect - create or break logical commection between import and export segments SYNOPSIS
cc [ flag... ] file... -lrsm [ library... ] #include <rsmapi.h> int rsm_memseg_import_connect(rsmapi_controller_handle_t controller, rsm_node_id_t nodeid, rsm_memseg_id_t segment_id, rsm_permission_t perm, rsm_memseg_import_handle_t *memseg); int rsm_memseg_import_disconnect(rsm_memseg_import_handle_t memseg); DESCRIPTION
The rsm_memseg_import_connect() function provides a means of creating an import segment called memseg and establishing a logical connection with an export segment identified by the segment_id on the node specified by node_id. The controller specified by controller must have a physical connection with the controller (see rsm_get_interconnect_topology(3RSM)) used while exporting the segment identified by segment_id on node specified by node_id. The perm argument specifies the mode of access that the importer is requesting for this connection. In the connection process, the mode of access and the importers userid and groupid are compared with the access permissions specified by the exporter. If the request mode is not valid, the connection request is denied. The perm argument is limited to the following octal values: 0400 read mode 0200 write mode 0600 read/write mode The rsm_memseg_import_disconnect() function breaks the logical connection between the import segment and the exported segment and deallo- cates the resources associated with the import segment handle memseg. RETURN VALUES
Upon successful completion, these functions return 0. Otherwise, an error value is returned to indicate the error. ERRORS
The rsm_memseg_import_connect() and rsm_memseg_import_disconnect() functions can return the following errors: RSMERR_BAD_SEG_HNDL Invalid segment handle. The rsm_memseg_import_connect() function can return the following errors: RSMERR_BAD_CTLR_HNDL Invalid controller handle. RSMERR_CTLR_NOT_PRESENT Controller not present. RSMERR_PERM_DENIED Permission denied. RSMERR_INSUFFICIENT_MEM Insufficient memory. RSMERR_INSUFFICIENT_RESOURCES Insufficient resources. RSMERR_SEG_NOT_PUBLISHED_TO_NODE Segment not published to node. RSMERR_SEG_NOT_PUBLISHED Segment not published at all. RSMERR_BAD_ADDR Bad address. RSMERR_REMOTE_NODE_UNREACHABLE Remote not not reachable. RSMERR_INTERRUPTED Connection interrupted. The rsm_memseg_import_disconnect() function can return the following errors: RSMERR_SEG_STILL_MAPPED Segment still mapped, need to unmap before disconnect. RSMERR_POLLFD_IN_USE Poll file descriptor in use. ATTRIBUTES
