NAME

       gnutls_x509_crq_get_subject_alt_name - API function

SYNOPSIS

       #include <gnutls/x509.h>

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

ARGUMENTS

       gnutls_x509_crq_t crq
                   should contain a gnutls_x509_crq_t type

       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_subject_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
