NAME    [Toc]    [Back]

       SSL_get_ex_data_X509_STORE_CTX_idx  - Get ex_data index to
       access SSL structure from X509_STORE_CTX

SYNOPSIS    [Toc]    [Back]

       #include <openssl/ssl.h>

       int SSL_get_ex_data_X509_STORE_CTX_idx(
               void );

DESCRIPTION    [Toc]    [Back]

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

NOTES    [Toc]    [Back]

       Whenever an X509_STORE_CTX object is created for the verification
  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             the
       SSL_get_ex_data_X509_STORE_CTX_idx() function.  The  index
       value is set when the SSL_get_ex_data_X509_STORE_CTX_idx()
       function 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    [Toc]    [Back]

       The index value to access the pointer.  An error occurred;
       check the error stack for a detailed error message.

EXAMPLES    [Toc]    [Back]

       The        index         returned         from         the
       SSL_get_ex_data_X509_STORE_CTX_idx()  function  allows you
       to access the SSL object for the connection to be accessed
       during  the  verify_callback()  function when checking the
       peers certificate. Check the example  in  SSL_CTX_set_verify(3).
