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_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  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_MEM-
       ORY_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 cer-
       tificate does not have an Alternative name with the specified sequence number then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.
