Синопсис (Synopsis)
#include <gnutls/x509.h>
void
gnutls_x509_trust_list_set_getissuer_function(gnutls_x509_trust_list_t
tlist, gnutls_x509_trust_list_getissuer_function * func);
Аргументы (Arguments)
gnutls_x509_trust_list_t tlist
is a gnutls_x509_trust_list_t type.
gnutls_x509_trust_list_getissuer_function * func
is the callback function
Описание (Description)
This function sets a callback to be called when the peer's
certificate chain is incomplete due a missing intermediate
certificate. The callback may provide the missing certificate for
use during verification.
The callback's function prototype is defined in <gnutls/x509.h>
as:
int (*callback)(gnutls_x509_trust_list_t list, const
gnutls_x509_crt_t cert, gnutls_x509_crt_t **issuers, unsigned int
*issuers_size);
If the callback function is provided then gnutls will call it
during the certificate verification procedure. The callback may
wish to use gnutls_x509_crt_get_authority_info_access() to get a
URI from which to attempt to download the missing issuer
certificate, if available.
On a successful call, the callback shall allocate the 'issuers'
array with gnutls_x509_crt_list_import2(). The ownership of both
the array and the elements is transferred to the caller and thus
the application does not need to maintain the memory after the
call.
The callback function should return 0 if the missing issuer
certificate for 'crt' was properly populated and added to the
'issuers', or non-zero to continue the certificate list
verification but with issuer as NULL.
