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_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:
