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.
