gnutls_x509_crq_get_subject_alt_name(3)       gnutls	  gnutls_x509_crq_get_subject_alt_name(3)

NAME
       gnutls_x509_crq_get_subject_alt_name - Get certificate's alternative name

SYNOPSIS
       #include <gnutls/x509.h>

       int  gnutls_x509_crq_get_subject_alt_name(gnutls_x509_crq_t cert, unsigned int seq, void *
       ret, size_t * ret_size, unsigned int * ret_type, unsigned int * critical);

ARGUMENTS
       gnutls_x509_crq_t cert
		   should contain a gnutls_x509_crq_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 gnutls_x509_subject_alt_name_t name type

       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_crq_get_subject_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_sub-
       ject_alt_name_t.   It  will  return  GNUTLS_E_SHORT_MEMORY_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	certificate request does not have an Alternative name with the specified sequence
       number then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.

SINCE
       2.8.0
