The branch master has been updated
       via  d318389eff0fb80d4a88c7af1cc314f185ba94e1 (commit)
      from  c89799605b833f769ce4cfd879bb291f49b133be (commit)

commit d318389eff0fb80d4a88c7af1cc314f185ba94e1
Author: Rich Salz <rsalz at akamai.com>
Date:   Fri Oct 18 12:24:39 2019 -0400

    Document "get/set-app-data" macros.
    
    Documenting the macros removes 14 undocumented items.
    Merged three separate manpages into one.
    Rename the DRBG CRYPTO_EX define into RAND_DRBG, but keep the old one
    for API compatibility.

-=head1 DESCRIPTION
-
-RAND_DRBG_set_ex_data() enables an application to store arbitrary application
-specific data B<data> in a RAND_DRBG instance B<drbg>. The index B<idx> should
-be a value previously returned from a call to RAND_DRBG_get_ex_new_index().
-
-RAND_DRBG_get_ex_data() retrieves application specific data previously stored
-in an RAND_DRBG instance B<drbg>. The B<idx> value should be the same as that
-used when originally storing the data.
-
-For more detailed information see L<CRYPTO_get_ex_data(3)> and
-L<CRYPTO_set_ex_data(3)> which implement these functions and
-L<CRYPTO_get_ex_new_index(3)> for generating a unique index.
-
-=head1 RETURN VALUES
-
-RAND_DRBG_set_ex_data() returns 1 for success or 0 for failure.
-
-RAND_DRBG_get_ex_data() returns the previously stored value or NULL on
-failure. NULL may also be a valid value.
-
-
-=head1 NOTES
-
-RAND_DRBG_get_ex_new_index(...) is implemented as a macro and equivalent to
-CRYPTO_get_ex_new_index(CRYPTO_EX_INDEX_DRBG,...).

-
-SSL*_set_ex_data() functions can be used to store arbitrary user data into the
