BIO_GET_EX_NEW_INDEX(3)                     DragonFly Library Functions Manual

NAME

BIO_get_ex_new_index, BIO_set_ex_data, BIO_get_ex_data, ENGINE_get_ex_new_index, ENGINE_set_ex_data, ENGINE_get_ex_data, UI_get_ex_new_index, UI_set_ex_data, UI_get_ex_data, X509_get_ex_new_index, X509_set_ex_data, X509_get_ex_data, EC_KEY_get_ex_new_index, EC_KEY_get_ex_data, EC_KEY_set_ex_data, ECDH_get_ex_new_index, ECDH_set_ex_data, ECDH_get_ex_data, ECDSA_get_ex_new_index, ECDSA_set_ex_data, ECDSA_get_ex_data - application-specific data

SYNOPSIS

#include <openssl/bio.h> #include <openssl/engine.h> #include <openssl/ui.h> #include <openssl/x509.h> #include <openssl/ec.h> #include <openssl/ecdh.h> #include <openssl/ecdsa.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 in OpenSSL data structures. Their usage is identical to that of RSA_get_ex_new_index(3), RSA_set_ex_data(3), and RSA_get_ex_data(3). 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.
