.. \*(C` and \*(C' are quotes 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'.

Title "BIO_get_ex_new_index 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.

The following functions have been deprecated since OpenSSL 3.0, and can be hidden entirely by defining OPENSSL_API_COMPAT with a suitable version value, see openssl_user_macros\|(7):

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

All functions with a TYPE of DH, DSA, RSA and EC_KEY 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 TYPE of ENGINE 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 TYPE object.

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

For compatibility with previous releases, the exdata index of zero is reserved for "application data." 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 NULL 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.
