DAT_RMR_CREATE 3DAT "Jul 16, 2004"
NAME
dat_rmr_create - create an RMR for the specified Protection Zone
SYNOPSIS

cc [ flag.\|.\|. ] file.\|.\|. -ldat [ library.\|.\|. ]
#include <dat/udat.h>

DAT_RETURN
 dat_rmr_create(
 IN DAT_PZ_HANDLE pz_handle,
 OUT DAT_RMR_HANDLE *rmr_handle
 )
PARAMETERS
pz_handle

Handle for an instance of the Protection Zone.

rmr_handle

Handle for the created instance of an RMR.

DESCRIPTION

The dat_rmr_create() function creates an RMR for the specified Protection Zone. This operation is relatively heavy. The created RMR can be bound to a memory region within the LMR through a lightweight dat_rmr_bind(3DAT) operation that generates rmr_context.

If the operation fails (does not return DAT_SUCCESS), the return values of rmr_handle are undefined and Consumers should not use them.

The pz_handle parameter provide Consumers a way to restrict access to an RMR by authorized connection only.

RETURN VALUES
DAT_SUCCESS

The operation was successful.

DAT_INSUFFICIENT_RESOURCES

The operation failed due to resource limitations.

DAT_INVALID_HANDLE

The pz_handle parameter is invalid.
