.SH DESCRIPTION
.sp
.LP
The \fBrsm_memseg_import_init_barrier()\fR function creates a barrier for the
imported segment specified by \fImemseg\fR. The barrier type is specified by
the \fItype\fR argument. Currently, only \fBRSM_BAR_DEFAULT\fR is supported as
a barrier type. A handle to the barrier is obtained through the \fIbarrier\fR
argument and is used in subsequent barrier calls.
.sp
.LP
The \fBrsm_memseg_import_destroy_barrier()\fR function deallocates all the
resources associated with the barrier.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, these functions return 0. Otherwise, an error value
is returned to indicate the error.
