* Name: ipv6_getsockopt
|
|
*
|
|
* Description:
|
|
* ipv6_getsockopt() 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.
