gnutls_x509_crt_get_issuer_alt_name2(3)                                 gnutls


NAME

       gnutls_x509_crt_get_issuer_alt_name2 - API function


SYNOPSIS

       #include <gnutls/x509.h>

       int gnutls_x509_crt_get_issuer_alt_name2(gnutls_x509_crt_t cert,
       unsigned int seq, void * ian, size_t * ian_size, unsigned int *
       ian_type, unsigned int * critical);


ARGUMENTS

       gnutls_x509_crt_t cert
                   should contain a gnutls_x509_crt_t type

       unsigned int seq
                   specifies the sequence number of the alt name (0 for the
                   first one, 1 for the second etc.)

       void * ian  is the place where the alternative name will be copied to

       size_t * ian_size
                   holds the size of ret.

       unsigned int * ian_type
                   holds the type of the alternative name (one of
                   gnutls_x509_subject_alt_name_t).

       unsigned int * critical
                   will be non-zero if the extension is marked as critical
                   (may be null)


DESCRIPTION

       This function will return the alternative names, contained in the given
       certificate. It is the same as gnutls_x509_crt_get_issuer_alt_name()
       except for the fact that it will return the type of the alternative
       name in  ian_type even if the function fails for some reason (i.e.  the
       buffer provided is not enough).


RETURNS

       the alternative issuer name type on success, one of the enumerated
       gnutls_x509_subject_alt_name_t.  It will return
       GNUTLS_E_SHORT_MEMORY_BUFFER if  ian_size is not large enough to hold
       the value.  In that case  ian_size will be updated with the required
       size.  If the certificate does not have an Alternative name with the
       specified sequence number then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is
       returned.


SINCE

       2.10.0
