=head1 DESCRIPTION
 | 
						|
 | 
						|
In the description here, I<TYPE> is used a placeholder
 | 
						|
for any of the OpenSSL datatypes listed in L<CRYPTO_get_ex_new_index(3)>.
 | 
						|
 | 
						|
All functions with a I<TYPE> of B<DH>, B<DSA>, B<RSA> and B<EC_KEY> are deprecated.
 | 
						|
Applications should instead use EVP_PKEY_set_ex_data(),
 | 
						|
EVP_PKEY_get_ex_data() and EVP_PKEY_get_ex_new_index().
 | 
						|
 | 
						|
All functions with a I<TYPE> of B<ENGINE> are deprecated.
 | 
						|
Applications using engines should be replaced by providers.
 | 
						|
 | 
						|
These functions handle application-specific data for OpenSSL data
 | 
						|
structures.
 | 
						|
 | 
						|
TYPE_get_ex_new_index() is a macro that calls CRYPTO_get_ex_new_index()
 | 
						|
with the correct B<index> value.
 | 
						|
 | 
						|
TYPE_set_ex_data() is a function that calls CRYPTO_set_ex_data() with
 | 
						|
an offset into the opaque exdata part of the TYPE object.
 | 
						|
 | 
						|
TYPE_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.
 | 
						|
TYPE_set_app_data() is a macro that invokes TYPE_set_ex_data() with
 | 
						|
B<idx> set to zero.
 | 
						|
TYPE_get_app_data() is a macro that invokes TYPE_get_ex_data() with
 | 
						|
B<idx> set to zero.
 | 
						|
 | 
						|
=head1 RETURN VALUES
 | 
						|
 | 
						|
TYPE_get_ex_new_index() returns a new index on success or -1 on error.
 | 
						|
 | 
						|
TYPE_set_ex_data() returns 1 on success or 0 on error.
 | 
						|
 | 
						|
TYPE_get_ex_data() returns the application data or NULL if an error occurred.
 | 
						|
 | 
						|

 |
