Handle for an instance of a Connection Request.
Mask for Connection Request parameters.
Pointer to a Consumer-allocated structure that the Provider fills for Consumer-requested parameters.
The dat_cr_query() function provides to the Consumer parameters of the Connection Request. The Consumer passes in a pointer to the Consumer-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.
The operation was successful
The cr_handle handle is invalid.
The cr_param_mask parameter is invalid.
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 private_data and its size.
