    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(const 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 manipulate 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

    ssl(3), RSA_get_ex_new_index(3), CRYPTO_set_ex_data(3), SSL_CTX_set_verify(3)
