SYNOPSIS

       #include <gnutls/x509.h>

       int  gnutls_x509_crt_get_dn_oid(gnutls_x509_crt_t  cert,  int  indx,  void * oid, size_t *
       oid_size);

ARGUMENTS

       gnutls_x509_crt_t cert
                   should contain a gnutls_x509_crt_t type

       int indx    This specifies which OID to return. Use (0) to get the first one.

       void * oid  a pointer to a buffer to hold the OID (may be null)

       size_t * oid_size
                   initially holds the size of  oid

DESCRIPTION

       This function will extract the OIDs of the name of the Certificate  subject  specified  by
       the given index.

       If   oid  is  null  then  only  the  size  will  be filled. The  oid returned will be null
       terminated, although  oid_size will not account for the trailing null.

RETURNS

       GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long enough, and in  that  case
       the       buf_size      will      be      updated      with     the     required     size.
       GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if there are  no  data  in  the  current  index.  On
       success 0 is returned.
