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(3) with the correct index value.

TYPE_set_ex_data() is a function that calls CRYPTO_set_ex_data(3) 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(3) with an offset into the opaque exdata part of the TYPE object.
