Hi all,
>From man page of SSL_CTX_set_verify, I saw this example snippet:
/*********************** snippet begin *********************************/
...
mydata_t mydata;
...
mydata_index = SSL_get_ex_new_index(0, "mydata index", NULL, NULL,
NULL);
...
SSL_set_ex_data(ssl, mydata_index, &mydata);
/*********************** snippet end *********************************/
My questions are:
1. Why it gets index from a global instead of from the specific ssl session
context?
2. This returned index increased for each time even for different ssl
connection, I don't know why, though I saw some comments in manpage of
RSA_get_ex_new_index, saying "Each successful call to RSA_get_ex_new_index()
will return an index greater than any previously returned, this is important
because the optional functions are called in order of increasing index value."
But I can't understand why "this is important".
3. If I have multiple simultaneous ssl connections, for each connection, can I
NOT call SSL_get_ex_new_index, and store my private data by directly writing
to index 0 position, e.g. SSL_set_ex_data(ssl, 0, &mydata) ? Then I get back
the data in by calling mydata = SSL_get_ex_data(ssl,0).
Thanks for your attention.
