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.
RETURN VALUES
TYPE_get_new_ex_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.
