NAME
       gnutls_x509_crt_get_subject_alt_name2 - API function


SYNOPSIS
       #include <gnutls/x509.h>

       int  gnutls_x509_crt_get_subject_alt_name2(gnutls_x509_crt_t cert, unsigned int seq, void * san, size_t *
       san_size, unsigned int * san_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 * san  is the place where the alternative name will be copied to

       size_t * san_size
                   holds the size of ret.

       unsigned int * san_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_subject_alt_name()  except  for  the  fact  that  it  will  return  the  type  of the
       alternative name in  san_type even if the function fails for some reason (i.e.  the  buffer  provided  is
       not enough).


RETURNS
       the  alternative  subject name type on success, one of the enumerated gnutls_x509_subject_alt_name_t.  It
       will return GNUTLS_E_SHORT_MEMORY_BUFFER if  san_size is not large enough to hold  the  value.   In  that
       case   san_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.
