DESCRIPTION

71       In the description here, TYPE is used a placeholder for any of the
72       OpenSSL datatypes listed in CRYPTO_get_ex_new_index(3).
73
74       All functions with a TYPE of DH, DSA, RSA and EC_KEY are deprecated.
75       Applications should instead use EVP_PKEY_set_ex_data(),
76       EVP_PKEY_get_ex_data() and EVP_PKEY_get_ex_new_index().
77
78       All functions with a TYPE of ENGINE are deprecated.  Applications using
79       engines should be replaced by providers.
80
81       These functions handle application-specific data for OpenSSL data
82       structures.
83
84       TYPE_get_ex_new_index() is a macro that calls CRYPTO_get_ex_new_index()
85       with the correct index value.
86
87       TYPE_set_ex_data() is a function that calls CRYPTO_set_ex_data() with
88       an offset into the opaque exdata part of the TYPE object.
89
90       TYPE_get_ex_data() is a function that calls CRYPTO_get_ex_data() with
91       an offset into the opaque exdata part of the TYPE object.
92
93       For compatibility with previous releases, the exdata index of zero is
94       reserved for "application data." There are two convenience functions
95       for this.  TYPE_set_app_data() is a macro that invokes
96       TYPE_set_ex_data() with idx set to zero.  TYPE_get_app_data() is a
97       macro that invokes TYPE_get_ex_data() with idx set to zero.
98

RETURN VALUES

100       TYPE_get_ex_new_index() returns a new index on success or -1 on error.
101
102       TYPE_set_ex_data() returns 1 on success or 0 on error.
103
104       TYPE_get_ex_data() returns the application data or NULL if an error
105       occurred.
