 RSM_MEMSEG_IMPORT_INIT_BARRIER 3RSM "Jun 8, 2001"
 NAME
rsm_memseg_import_init_barrier, rsm_memseg_import_destroy_barrier - create or
destroy barrier for imported segment
 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

The rsm_memseg_import_init_barrier() and
rsm_memseg_import_destroy_barrier() functions can return the following
errors:
RSMERR_BAD_SEG_HNDL

Invalid segment handle.


RSMERR_BAD_BARRIER_PTR

The rsm_memseg_import_init_barrier() function can return the following
errors:
