X509_STORE_CTX_get_ex_new_index, X509_STORE_CTX_set_ex_data, X509_STORE_CTX_get_ex_data - add application specific data to X509_STORE_CTX structures
#include <openssl/x509_vfy.h>
int X509_STORE_CTX_get_ex_new_index(long argl, void *argp, CRYPTO_EX_new *new_func, CRYPTO_EX_dup *dup_func, CRYPTO_EX_free *free_func);
int X509_STORE_CTX_set_ex_data(X509_STORE_CTX *d, int idx, void *arg);
void *X509_STORE_CTX_get_ex_data(X509_STORE_CTX *d, int idx);
These functions handle application specific data in X509_STORE_CTX 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 RSA_get_ex_new_index(3).
This mechanism is used internally by the ssl library to store the SSL structure associated with a verification operation in an X509_STORE_CTX structure.
X509_STORE_CTX_get_ex_new_index(), X509_STORE_CTX_set_ex_data()
and
X509_STORE_CTX_get_ex_data()
are available since OpenSSL 0.9.5.
