1796 * gnutls_pin_callback_t:
1797 * @userdata: user-controlled data from gnutls_pkcs11_set_pin_function().
1798 * @attempt: pin-attempt counter, initially 0.
1799 * @token_url: URL of token.
1800 * @token_label: label of token.
1801 * @flags: a #gnutls_pin_flag_t flag.
1802 * @pin: buffer to hold PIN, of size @pin_max.
1803 * @pin_max: size of @pin buffer.
1804 *
1805 * Callback function type for PKCS#11 or TPM PIN entry. It is set by
1806 * functions like gnutls_pkcs11_set_pin_function().
1807 *
1808 * The callback should provides the PIN code to unlock the token with
1809 * label @token_label, specified by the URL @token_url.
1810 *
1811 * The PIN code, as a NUL-terminated ASCII string, should be copied
1812 * into the @pin buffer (of maximum size @pin_max), and return 0 to
1813 * indicate success. Alternatively, the callback may return a
1814 * negative gnutls error code to indicate failure and cancel PIN entry
1815 * (in which case, the contents of the @pin parameter are ignored).
1816 *
1817 * When a PIN is required, the callback will be invoked repeatedly
1818 * (and indefinitely) until either the returned PIN code is correct,
1819 * the callback returns failure, or the token refuses login (e.g. when
1820 * the token is locked due to too many incorrect PINs!). For the
1821 * first such invocation, the @attempt counter will have value zero;
1822 * it will increase by one for each subsequent attempt.
1823 *
1824 * Returns: %GNUTLS_E_SUCCESS (0) on success or a negative error code on error.
1825 *
1826 * Since: 2.12.0
