rsm_memseg_import_set_mode(3RSM)		      Remote Shared Memory Library Functions			  rsm_memseg_import_set_mode(3RSM)

NAME

       rsm_memseg_import_set_mode, rsm_memseg_import_get_mode - set or get mode for barrier scoping

SYNOPSIS

       cc [ flag... ] file... -lrsm [ library... ]
       #include <rsmapi.h>

       int rsm_memseg_import_set_mode(rsm_memseg_import_handle_t memseg, rsm_barrier_mode_t mode);

       int rsm_memseg_import_get_mode(rsm_memseg_import_handle_t memseg, rsm_barrier_mode_t *mode);

DESCRIPTION

       The   rsm_memseg_import_set_mode()  function  provides  support	for  optional  explicit  barrier scoping in the functions described on the
       rsm_memseg_import_get(3RSM) and rsm_memseg_import_put(3RSM) manual pages.. The two valid barrier modes  are  RSM_BARRIER_MODE_EXPLICIT  and
       RSM_BARRIER_MODE_IMPLICIT. By default, the barrier mode is set to RSM_BARRIER_MODE_IMPLICIT. When the mode is RSM_BARRIER_MODE_IMPLICIT, an
       implicit barrier open and barrier close is applied to the put operation.  Irrespective of the mode set, the  barrier  must  be  initialized
       using the  rsm_memseg_import_init_barrier(3RSM) function before any barrier operations, either implicit or explicit, are used.

       The rsm_memseg_import_get_mode() function obtains the current value of the mode used for barrier scoping in put functions.

RETURN VALUES

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

ERRORS

       The rsm_memseg_import_set_mode() and rsm_memseg_import_get_mode() functions can return the following errors:

       RSMERR_BAD_SEG_HNDL     Invalid segment handle.

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  bar-
       rier 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_barrier() 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.
