Helpers for IPv6 Options (1)

• int inet6_opt_init(void *extbuf, socklen_t extlen);

  • Initialize buffer data for options header

• int inet6_opt_append(void *extbuf, socklen_t extlen,

  • int offset, uint8_t type, socklen_t len,
  • uint_t align, void **databufp);
  • Add one TLV option to the option header

• uint8_t *inet6_opt_finish(void *extbuf, socklen_t extlen,

  • int offset);
  • Finish adding TLV options to the options header

• int inet6_opt_set_val(void *databuf, int offset, void *val,

  • socklen_t vallen);
  • Add one component of the option content to the option
