NAME
dat_rmr_query - provide RMR parameters
SYNOPSIS

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

DAT_RETURN
 dat_rmr_query (
 IN DAT_RMR_HANDLE rmr_handle,
 IN DAT_RMR_PARAM_MASK rmr_param_mask,
 OUT DAT_RMR_PARAM *rmr_param
 )
PARAMETERS
rmr_handle

Handle for an instance of the RMR.

rmr_param_mask

Mask for RMR parameters.

rmr_param

Pointer to a Consumer-allocated structure that the Provider fills with RMR parameters.

DESCRIPTION

The dat_rmr_query() function provides RMR parameters to the Consumer. The Consumer passes in a pointer to the Consumer-allocated structures for RMR parameters that the Provider fills.

The rmr_param_mask parameter allows Consumers to specify which parameters to query. The Provider returns values for rmr_param_mask requested parameters. The Provider can return values for any other parameters.

Not all parameters can have a value at all times. For example, lmr_handle, target_address, segment_length, mem_privileges, and rmr_context are not defined for an unbound RMR.

RETURN VALUES
DAT_SUCCESS

The operation was successful.

DAT_INVALID_PARAMETER

The rmr_param_mask parameter is invalid.

DAT_INVALID_HANDLE

The mr_handle parameter is invalid.
