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.
