| =head1 DESCRIPTION |
| |
| Several OpenSSL structures can have application specific data attached to them. |
| These functions are used internally by OpenSSL to manipulate application |
| specific data attached to a specific structure. |
| |
| SSL_CTX_get_ex_new_index() is used to register a new index for application |
| specific data. |
| |
| SSL_CTX_set_ex_data() is used to store application data at B<arg> for B<idx> |
| into the B<ctx> object. |
| |
| SSL_CTX_get_ex_data() is used to retrieve the information for B<idx> from |
| B<ctx>. |
| |
| A detailed description for the B<*_get_ex_new_index()> functionality |
| can be found in L<RSA_get_ex_new_index(3)|RSA_get_ex_new_index(3)>. |
| The B<*_get_ex_data()> and B<*_set_ex_data()> functionality is described in |
| L<CRYPTO_set_ex_data(3)|CRYPTO_set_ex_data(3)>. |
