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_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 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
