|  | =head1 NAME | 
|  |  | 
|  | DH_get_ex_new_index, DH_set_ex_data, DH_get_ex_data - add application specific data to DH structures | 
|  |  | 
|  | =head1 SYNOPSIS | 
|  |  | 
|  | #include <openssl/dh.h> | 
|  |  | 
|  | int DH_get_ex_new_index(long argl, void *argp, | 
|  | CRYPTO_EX_new *new_func, | 
|  | CRYPTO_EX_dup *dup_func, | 
|  | CRYPTO_EX_free *free_func); | 
|  |  | 
|  | int DH_set_ex_data(DH *d, int idx, void *arg); | 
|  |  | 
|  | char *DH_get_ex_data(DH *d, int idx); | 
|  |  | 
|  | =head1 DESCRIPTION | 
|  |  | 
|  | These functions handle application specific data in DH | 
|  | structures. Their usage is identical to that of | 
|  | RSA_get_ex_new_index(), RSA_set_ex_data() and RSA_get_ex_data() | 
|  | as described in L<RSA_get_ex_new_index(3)>. | 
|  |  |

|  |  | 
|  | L<RSA_get_ex_new_index(3)|RSA_get_ex_new_index(3)>, L<dh(3)|dh(3)> | 
|  |  | 
|  | =head1 HISTORY | 
|  |  | 
|  | DH_get_ex_new_index(), DH_set_ex_data() and DH_get_ex_data() are | 
|  | available since OpenSSL 0.9.5. |
