Function obj_txn_begin_read 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn obj_txn_begin_read(
    db: *mut obj_db_t,
    out_txn: *mut *mut obj_read_txn_t,
) -> obj_error_t

Begin a read transaction against db. Pins a snapshot at the current writer LSN.

Safety

• db must be a valid handle returned by obj_open*.
• out_txn must be a writable obj_read_txn_t *.
