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
