DESCRIPTION

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.  

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 private_data and its size.
