SYNOPSIS

21        #include <openssl/x509.h>
22
23        int TYPE_get_ex_new_index(long argl, void *argp,
24                                  CRYPTO_EX_new *new_func,
25                                  CRYPTO_EX_dup *dup_func,
26                                  CRYPTO_EX_free *free_func);
27
28        int TYPE_set_ex_data(TYPE *d, int idx, void *arg);
29
30        void *TYPE_get_ex_data(TYPE *d, int idx);

DESCRIPTION

33       In the description here, TYPE is used a placeholder for any of the
34       OpenSSL datatypes listed in CRYPTO_get_ex_new_index(3).
35
36       These functions handle application-specific data for OpenSSL data
37       structures.
38
39       TYPE_get_ex_new_index() is a macro that calls CRYPTO_get_ex_new_index()
40       with the correct index value.
41
42       TYPE_set_ex_data() is a function that calls CRYPTO_set_ex_data() with
43       an offset into the opaque exdata part of the TYPE object.
44
45       TYPE_get_ex_data() is a function that calls CRYPTO_get_ex_data() with
46       an offset into the opaque exdata part of the TYPE object.
47

RETURN VALUES

49       TYPE_get_ex_new_index() returns a new index on success or -1 on error.
50
51       TYPE_set_ex_data() returns 1 on success or 0 on error.
52
53       TYPE_get_ex_data() returns the application data or NULL if an error
54       occurred.
