typedef struct client_context {
  uint64_t                       ns_threshold;
  uint64_t                       last_ns;
  uint32_t                       last_cpu;
  bool                           flush;
  bool                           only_one_cpu;
  uint64_t                       counter;
  SLIST_HEAD( , client_item )    free_items;
  RB_HEAD( active, client_item ) active_items;
} client_context;

to

typedef struct client_context {
  uint64_t                       ns_threshold;
  uint64_t                       last_ns;
  uint32_t                       last_cpu;
  bool                           flush;
  bool                           only_one_cpu;
  uint64_t                       counter;
  SLIST_HEAD( , client_item )    free_items;
  RB_HEAD( active, client_item ) active_items;
  FILE                           *fptr;
} client_context;

In this case, I have to create global client_context variable to store the
file pointer in it. Is that good?
