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_bar‐
rier() functions can return the following errors:
RSMERR_BAD_SEG_HNDL Invalid segment handle.
RSMERR_BAD_BARRIER_PTR Invalid barrier pointer.
The rsm_memseg_import_init_barrier() function can return the following
errors:
RSMERR_INSUFFICIENT_MEM Insufficient memory.
