- * Name: ipv6_setsockopt
- *
- * Description:
- * ipv6_setsockopt() sets the IPv6-protocol socket option specified by the
- * 'option' argument to the value pointed to by the 'value' argument for
- * the socket specified by the 'psock' argument.
- *
- * See <netinet/in.h> for the a complete list of values of IPv6 protocol
- * socket options.
- *
- * Input Parameters:
- * psock Socket structure of socket to operate on
- * option identifies the option to set
- * value Points to the argument value
- * value_len The length of the argument value
- *
- * Returned Value:
- * Returns zero (OK) on success. On failure, it returns a negated errno
- * value to indicate the nature of the error. See psock_setcockopt() for
- * the list of possible error values.
