# NAME

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

# SYNOPSIS

     #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);

# DESCRIPTION

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).

# NOTES

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.

# SEE ALSO

RSA_get_ex_new_index

# HISTORY

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.
