NAME

SSL_SESSION_set_ex_data, SSL_SESSION_get_ex_data - get and set application specific data on a session

SYNOPSIS

 #include <openssl/ssl.h>
 int SSL_SESSION_set_ex_data(SSL_SESSION *ss, int idx, void *data);
 void *SSL_SESSION_get_ex_data(const SSL_SESSION *s, int idx);

DESCRIPTION

SSL_SESSION_set_ex_data() enables an application to store arbitrary application specific data data in an SSL_SESSION structure ss. The index idx should be a value previously returned from a call to CRYPTO_get_ex_new_index(3).

SSL_SESSION_get_ex_data() retrieves application specific data previously stored in an SSL_SESSION structure s. The idx value should be the same as that used when originally storing the data.

RETURN VALUES

SSL_SESSION_set_ex_data() returns 1 for success or 0 for failure.

SSL_SESSION_get_ex_data() returns the previously stored value or NULL on failure. NULL may also be a valid value.
