rsm_memseg_import_init_barrier, rsm_memseg_import_destroy_barrier - create or destroy barrier for imported segment

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);

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.

Upon successful completion, these functions return 0. Otherwise, an error value is returned to indicate the error.

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

RSMERR_BAD_BARRIER_PTR

The rsm_memseg_import_init_barrier() function can return the following errors: RSMERR_INSUFFICIENT_MEM
