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.

SEE ALSO

CRYPTO_get_ex_new_index(3).
