CRYPTO_set_ex_data(3)			     OpenSSL			    CRYPTO_set_ex_data(3)

       CRYPTO_set_ex_data, CRYPTO_get_ex_data - internal application specific data functions

	int CRYPTO_set_ex_data(CRYPTO_EX_DATA *r, int idx, void *arg);

	void *CRYPTO_get_ex_data(CRYPTO_EX_DATA *r, int idx);

       Several OpenSSL structures can have application specific data attached to them.	These
       functions are used internally by OpenSSL to manipulate application specific data attached
       to a specific structure.

       These functions should only be used by applications to manipulate CRYPTO_EX_DATA struc-
       tures passed to the new_func(), free_func() and dup_func() callbacks: as passed to
       RSA_get_ex_new_index() for example.

       CRYPTO_set_ex_data() is used to set application specific data, the data is supplied in the
       arg parameter and its precise meaning is up to the application.

       CRYPTO_get_ex_data() is used to retrieve application specific data. The data is returned
       to the application, this will be the same value as supplied to a previous
       CRYPTO_set_ex_data() call.

       CRYPTO_set_ex_data() returns 1 on success or 0 on failure.

       CRYPTO_get_ex_data() returns the application data or 0 on failure. 0 may also be valid
       application data but currently it can only fail if given an invalid idx parameter.

       On failure an error code can be obtained from ERR_get_error(3).

       RSA_get_ex_new_index(3), DSA_get_ex_new_index(3), DH_get_ex_new_index(3)

       CRYPTO_set_ex_data() and CRYPTO_get_ex_data() have been available since SSLeay 0.9.0.
