X509_STORE_CTX_get_ex_data(3) add application specific data to X509_STORE_CTX structures

Other Alias

X509_STORE_CTX_get_ex_new_index, X509_STORE_CTX_set_ex_data


#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.
