Function hdds_reader_create_with_type 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn hdds_reader_create_with_type(
    participant: *mut HddsParticipant,
    topic_name: *const c_char,
    type_name: *const c_char,
    qos: *const HddsQoS,
) -> *mut HddsDataReader

Create a DataReader for a topic with custom QoS and explicit type name.

The type_name is announced via SEDP and must match the remote endpoint’s type name for topic matching (e.g. "P_Mount_PSM::C_Rotational_Mount_setPosition"). If type_name is NULL, falls back to the default "RawBytes" type name.

Safety

• participant must be a valid pointer returned from hdds_participant_create
• topic_name must be a valid null-terminated C string
• type_name must be a valid null-terminated C string (or NULL for default)
• qos must be a valid pointer returned from hdds_qos_* functions (or NULL for default)
