rsm_memseg_import_set_mode, rsm_memseg_import_get_mode - set or get
mode for barrier scoping
SYNOPSIS
cc [ flag... ] file... -lrsm [ library... ]
#include <rsmapi.h>
int rsm_memseg_import_set_mode(rsm_memseg_import_handle_t memseg,
rsm_barrier_mode_t mode);
int rsm_memseg_import_get_mode(rsm_memseg_import_handle_t memseg,
rsm_barrier_mode_t *mode);
DESCRIPTION
The rsm_memseg_import_set_mode() function provides support for
optional explicit barrier scoping in the functions described on the
rsm_memseg_import_get(3RSM) and rsm_memseg_import_put(3RSM) manual
pages.. The two valid barrier modes are RSM_BARRIER_MODE_EXPLICIT and
RSM_BARRIER_MODE_IMPLICIT. By default, the barrier mode is set to
RSM_BARRIER_MODE_IMPLICIT. When the mode is RSM_BARRIER_MODE_IMPLICIT,
an implicit barrier open and barrier close is applied to the put opera‐
tion. Irrespective of the mode set, the barrier must be initialized
using the rsm_memseg_import_init_barrier(3RSM) function before any
barrier operations, either implicit or explicit, are used.
The rsm_memseg_import_get_mode() function obtains the current value of
the mode used for barrier scoping in put functions.
RETURN VALUES
Upon successful completion, these functions return 0. Otherwise, an
error value is returned to indicate the error.
ERRORS
The rsm_memseg_import_set_mode() and rsm_memseg_import_get_mode() func‐
tions can return the following errors:
RSMERR_BAD_SEG_HNDL Invalid segment handle.
