=pod =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 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. =head1 SEE ALSO L, L =head1 HISTORY DH_get_ex_new_index(), DH_set_ex_data() and DH_get_ex_data() are available since OpenSSL 0.9.5. =cut
