     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.

     These functions should only be used by applications to
     manipulate CCCCRRRRYYYYPPPPTTTTOOOO_EEEEXXXX_DDDDAAAATTTTAAAA structures passed to the
     nnnneeeewwww_ffffuuuunnnncccc(((()))), ffffrrrreeeeeeee_ffffuuuunnnncccc(((()))) and dddduuuupppp_ffffuuuunnnncccc(((()))) callbacks: as passed
     to RRRRSSSSAAAA_ggggeeeetttt_eeeexxxx_nnnneeeewwww_iiiinnnnddddeeeexxxx(((()))) for example.

     CCCCRRRRYYYYPPPPTTTTOOOO_sssseeeetttt_eeeexxxx_ddddaaaattttaaaa(((()))) is used to set application specific
     data, the data is supplied in the aaaarrrrgggg parameter and its
     precise meaning is up to the application.

     CCCCRRRRYYYYPPPPTTTTOOOO_ggggeeeetttt_eeeexxxx_ddddaaaattttaaaa(((()))) is used to retrieve application
     specific data. The data is returned to the application, this
     will be the same value as supplied to a previous
     CCCCRRRRYYYYPPPPTTTTOOOO_sssseeeetttt_eeeexxxx_ddddaaaattttaaaa(((()))) call.

RRRREEEETTTTUUUURRRRNNNN VVVVAAAALLLLUUUUEEEESSSS
     CCCCRRRRYYYYPPPPTTTTOOOO_sssseeeetttt_eeeexxxx_ddddaaaattttaaaa(((()))) returns 1 on success or 0 on failure.

     CCCCRRRRYYYYPPPPTTTTOOOO_ggggeeeetttt_eeeexxxx_ddddaaaattttaaaa(((()))) returns the application data or 0 on
     failure. 0 may also be valid application data but currently
     it can only fail if given an invalid iiiiddddxxxx parameter.

     On failure an error code can be obtained from
     ERR_get_error(3).
