SSL_get_ex_new_index(3) 					      OpenSSL						   SSL_get_ex_new_index(3)

NAME
SSL_get_ex_new_index, SSL_set_ex_data, SSL_get_ex_data - internal application specific data functions SYNOPSIS
#include <openssl/ssl.h> int SSL_get_ex_new_index(long argl, void *argp, CRYPTO_EX_new *new_func, CRYPTO_EX_dup *dup_func, CRYPTO_EX_free *free_func); int SSL_set_ex_data(SSL *ssl, int idx, void *arg); void *SSL_get_ex_data(SSL *ssl, int idx); typedef int new_func(void *parent, void *ptr, CRYPTO_EX_DATA *ad, int idx, long argl, void *argp); typedef void free_func(void *parent, void *ptr, CRYPTO_EX_DATA *ad, int idx, long argl, void *argp); typedef int dup_func(CRYPTO_EX_DATA *to, CRYPTO_EX_DATA *from, void *from_d, int idx, long argl, void *argp); DESCRIPTION
Several OpenSSL structures can have application specific data attached to them. These functions are used internally by OpenSSL to manipu- late application specific data attached to a specific structure. SSL_get_ex_new_index() is used to register a new index for application specific data. SSL_set_ex_data() is used to store application data at arg for idx into the ssl object. SSL_get_ex_data() is used to retrieve the information for idx from ssl. A detailed description for the *_get_ex_new_index() functionality can be found in RSA_get_ex_new_index(3). The *_get_ex_data() and *_set_ex_data() functionality is described in CRYPTO_set_ex_data(3). EXAMPLES
An example on how to use the functionality is included in the example verify_callback() in SSL_CTX_set_verify(3). SEE ALSO

NAME
SSL_SESSION_get_ex_new_index, SSL_SESSION_set_ex_data, SSL_SESSION_get_ex_data - internal application specific data functions SYNOPSIS
#include <openssl/ssl.h> int SSL_SESSION_get_ex_new_index(long argl, void *argp, CRYPTO_EX_new *new_func, CRYPTO_EX_dup *dup_func, CRYPTO_EX_free *free_func); int SSL_SESSION_set_ex_data(SSL_SESSION *session, int idx, void *arg); void *SSL_SESSION_get_ex_data(SSL_SESSION *session, int idx); typedef int new_func(void *parent, void *ptr, CRYPTO_EX_DATA *ad, int idx, long argl, void *argp); typedef void free_func(void *parent, void *ptr, CRYPTO_EX_DATA *ad, int idx, long argl, void *argp); typedef int dup_func(CRYPTO_EX_DATA *to, CRYPTO_EX_DATA *from, void *from_d, int idx, long argl, void *argp); DESCRIPTION
Several OpenSSL structures can have application specific data attached to them. These functions are used internally by OpenSSL to manipu- late application specific data attached to a specific structure. SSL_SESSION_get_ex_new_index() is used to register a new index for application specific data. SSL_SESSION_set_ex_data() is used to store application data at arg for idx into the session object.

The application data is only maintained for sessions held in memory. The application data is not included when dumping the session with i2d_SSL_SESSION() (and all functions indirectly calling the dump functions like PEM_write_SSL_SESSION() and PEM_write_bio_SSL_SESSION()) and can therefore not be restored.
