gnutls_x509_crt_get_subject_alt_name2(3)      gnutls	 gnutls_x509_crt_get_subject_alt_name2(3)

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 structure

       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_sub-
		   ject_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_sub-
       ject_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.
