X509_STORE_CTX_GET_EX_NEW_INDEX(3) FreeBSD Library Functions Manual
NAME
X509_STORE_CTX_get_ex_new_index, X509_STORE_CTX_set_ex_data,
X509_STORE_CTX_get_ex_data, X509_STORE_CTX_set_app_data,
X509_STORE_CTX_get_app_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);
int
X509_STORE_CTX_set_app_data(X509_STORE_CTX *d, void *arg);
void *
X509_STORE_CTX_get_app_data(X509_STORE_CTX *d);
DESCRIPTION
These functions handle application specific data in X509_STORE_CTX
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).
This mechanism is used internally by the ssl(3) library to store the SSL
structure associated with a verification operation in an X509_STORE_CTX
structure.
X509_STORE_CTX_set_app_data() and X509_STORE_CTX_get_app_data() are
macros calling X509_STORE_CTX_set_ex_data() and
X509_STORE_CTX_get_ex_data(), respectively, with an idx of 0.
RETURN VALUES
X509_STORE_CTX_get_ex_new_index() returns a new index or -1 on failure.
X509_STORE_CTX_set_ex_data() and X509_STORE_CTX_set_app_data() return 1
on success or 0 on failure.
X509_STORE_CTX_get_ex_data() and X509_STORE_CTX_get_app_data() return the
application data or NULL on failure. NULL may also be valid application
data, but currently these functions can only fail if given an invalid idx
argument.

HISTORY
X509_STORE_CTX_set_app_data() and X509_STORE_CTX_get_app_data() first
appeared in SSLeay 0.8.0 and X509_STORE_CTX_get_ex_new_index(),
X509_STORE_CTX_set_ex_data(), and X509_STORE_CTX_get_ex_data() in SSLeay
0.9.0. All these functions have been available since OpenBSD 2.4.
