SYNOPSIS
cc [ flag... ] file... -lrsm [ library... ]
#include <rsmapi.h>
int rsm_memseg_import_init_barrier(
rsm_memseg_import_handle_t memseg, rsm_barrier_type_t type,
rsmapi_barrier_t *barrier);
int rsm_memseg_import_destroy_barrier(rsmapi_barrier_t *barrier);
DESCRIPTION
The rsm_memseg_import_init_barrier() function creates a barrier for the
imported segment specified by memseg. The barrier type is specified by
the type argument. Currently, only RSM_BAR_DEFAULT is supported as a
barrier type. A handle to the barrier is obtained through the barrier
argument and is used in subsequent barrier calls.
The rsm_memseg_import_destroy_barrier() function deallocates all the
resources associated with the barrier.
RETURN VALUES
Upon successful completion, these functions return 0. Otherwise, an
error value is returned to indicate the error.
ERRORS

rier() functions can return the following errors:
