NAME

       gnutls_x509_crt_get_subject_alt_name2 - Get certificate's alternative name, if any

SYNOPSIS

       #include <gnutls/x509.h>

       int gnutls_x509_crt_get_subject_alt_name2(gnutls_x509_crt_t cert, unsigned int seq, void * ret, size_t * ret_size, unsigned int * ret_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 * ret  is the place where the alternative name will be copied to

       size_t * ret_size
		   holds the size of ret.

       unsigned int * ret_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_sub-
       ject_alt_name()	except	for  the fact that it will return the type of the alternative name in ret_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_MEM-
       ORY_BUFFER  if  ret_size is not large enough to hold the value.	In that case ret_size will be updated with the required size.  If the cer-
       tificate does not have an Alternative name with the specified sequence number then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.
