NAME

       dat_cr_query - provide parameters of the Connection Request

SYNOPSIS

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

       DAT_RETURN
	   dat_cr_query (
	   IN	 DAT_CR_HANDLE	      cr_handle,
	   IN	 DAT_CR_PARAM_MASK    cr_param_mask,
	   OUT	 DAT_CR_PARAM	      *cr_param
	   )

PARAMETERS

       cr_handle       Handle for an instance of a Connection Request.

       cr_param_mask   Mask for Connection Request parameters.

       cr_param        Pointer to a Consumer-allocated structure that the Provider fills for Consumer-requested parameters.

DESCRIPTION

       The  dat_cr_query()  function  provides	to the Consumer parameters of the Connection Request. The Consumer passes in a pointer to the Con-
       sumer-allocated structures for Connection Request parameters that the Provider fills.

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

RETURN VALUES

       DAT_SUCCESS	       The operation was successful

       DAT_INVALID_HANDLE      The cr_handle handle is invalid.

       DAT_INVALID_PARAMETER   The cr_param_mask parameter is invalid.

USAGE

       The  Consumer  uses dat_cr_query() to get information about requesting a remote Endpoint as well as a local Endpoint if it was allocated by
       the Provider for the arrived Connection Request. The local Endpoint is created if the Consumer used PSP with DAT_PSP_PROVIDER as the  value
       for  psp_flags. For the remote Endpoint, dat_cr_query()	provides remote_ia_address and remote_port_qual. It also provides remote peer pri-
       vate_data and its size.
