DSA_get_ex_new_index, DSA_set_ex_data, DSA_get_ex_data
add application specific data to DSA structures

#include <openssl/dsa.h>

int
DSA_get_ex_new_index(long argl, void *argp, CRYPTO_EX_new *new_func, CRYPTO_EX_dup *dup_func, CRYPTO_EX_free *free_func);

int
DSA_set_ex_data(DSA *d, int idx, void *arg);

char *
DSA_get_ex_data(DSA *d, int idx);

These functions handle application specific data in DSA structures. Their usage is identical to that of RSA_get_ex_new_index(3), RSA_set_ex_data(3), and RSA_get_ex_data(3).
