.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Header "DESCRIPTION" In the description here, \s-1TYPE\s0 is used a placeholder for any of the OpenSSL datatypes listed in CRYPTO_get_ex_new_index\|(3).

All functions with a \s-1TYPE\s0 of \s-1DH\s0, \s-1DSA\s0, \s-1RSA\s0 and \s-1EC_KEY\s0 are deprecated. Applications should instead use EVP_PKEY_set_ex_data(), \fBEVP_PKEY_get_ex_data() and EVP_PKEY_get_ex_new_index().

All functions with a \s-1TYPE\s0 of \s-1ENGINE\s0 are deprecated. Applications using engines should be replaced by providers.

These functions handle application-specific data for OpenSSL data structures.

\fBTYPE_get_ex_new_index() is a macro that calls CRYPTO_get_ex_new_index() with the correct index value.

\fBTYPE_set_ex_data() is a function that calls CRYPTO_set_ex_data() with an offset into the opaque exdata part of the \s-1TYPE\s0 object.

\fBTYPE_get_ex_data() is a function that calls CRYPTO_get_ex_data() with an offset into the opaque exdata part of the \s-1TYPE\s0 object.

For compatibility with previous releases, the exdata index of zero is reserved for \*(L"application data.\*(R" There are two convenience functions for this. \fBTYPE_set_app_data() is a macro that invokes TYPE_set_ex_data() with \fBidx set to zero. \fBTYPE_get_app_data() is a macro that invokes TYPE_get_ex_data() with \fBidx set to zero.

Header "RETURN VALUES" \fBTYPE_get_ex_new_index() returns a new index on success or -1 on error.

\fBTYPE_set_ex_data() returns 1 on success or 0 on error.

\fBTYPE_get_ex_data() returns the application data or \s-1NULL\s0 if an error occurred.

Header "SEE ALSO" \fBCRYPTO_get_ex_new_index\|(3). Header "HISTORY" The functions DH_get_ex_new_index(), DH_set_ex_data(), DH_get_ex_data(), \fBDSA_get_ex_new_index(), DSA_set_ex_data(), DSA_get_ex_data(), \fBEC_KEY_get_ex_new_index(), EC_KEY_set_ex_data(), EC_KEY_get_ex_data(), \fBENGINE_get_ex_new_index(), ENGINE_set_ex_data(), ENGINE_get_ex_data(), \fBRSA_get_ex_new_index(), RSA_set_ex_data(), RSA_get_ex_data(), \fBRSA_set_app_data() and RSA_get_app_data() were deprecated in OpenSSL 3.0.
