SYNOPSIS
#include <openssl/x509.h>
int TYPE_get_ex_new_index(long argl, void *argp,
CRYPTO_EX_new *new_func,
CRYPTO_EX_dup *dup_func,
CRYPTO_EX_free *free_func);
int TYPE_set_ex_data(TYPE *d, int idx, void *arg);
void *TYPE_get_ex_data(TYPE *d, int idx);
DESCRIPTION
In the description here, TYPE is used a placeholder for any of the
OpenSSL datatypes listed in CRYPTO_get_ex_new_index(3).
These functions handle application-specific data for OpenSSL data
structures.
TYPE_get_ex_new_index() is a macro that calls CRYPTO_get_ex_new_index()
with the correct index value.
TYPE_set_ex_data() is a function that calls CRYPTO_set_ex_data() with
an offset into the opaque exdata part of the TYPE object.
TYPE_get_ex_data() is a function that calls CRYPTO_get_ex_data() with
an offset into the opaque exdata part of the TYPE object.
RETURN VALUES
TYPE_get_ex_new_index() returns a new index on success or -1 on error.
TYPE_set_ex_data() returns 1 on success or 0 on error.
TYPE_get_ex_data() returns the application data or NULL if an error
occurred.
