NAME
       SSL_get_ex_data_X509_STORE_CTX_idx - get ex_data index
       to access SSL structure from X509_STORE_CTX

SYNOPSIS
        #include <openssl/ssl.h>

        int SSL_get_ex_data_X509_STORE_CTX_idx(void);

DESCRIPTION
       SSL_get_ex_data_X509_STORE_CTX_idx() returns the index
       number under which the pointer to the SSL object is
       stored into the X509_STORE_CTX object.

NOTES
       Whenever a X509_STORE_CTX object is created for the ver-
       ification of the peers certificate during a handshake, a
       pointer to the SSL object is stored into the
       X509_STORE_CTX object to identify the connection
       affected.  To retrieve this pointer the
       X509_STORE_CTX_get_ex_data() function can be used with
       the correct index. This index is globally the same for
       all X509_STORE_CTX objects and can be retrieved using
       SSL_get_ex_data_X509_STORE_CTX_idx(). The index value is
       set when SSL_get_ex_data_X509_STORE_CTX_idx() is first
       called either by the application program directly or
       indirectly during other SSL setup functions or during
       the handshake.

       The value depends on other index values defined for
       X509_STORE_CTX objects before the SSL index is created.

RETURN VALUES
       >=0 The index value to access the pointer.

       <0  An error occurred, check the error stack for a
           detailed error message.

EXAMPLES
       The index returned from
       SSL_get_ex_data_X509_STORE_CTX_idx() allows to access
       the SSL object for the connection to be accessed during
       the verify_callback() when checking the peers certifi-
       cate. Please check the example in SSL_CTX_set_verify(3),
