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.
