NAME
       gnutls_x509_crt_get_dn_by_oid - This function returns the Certificate's distinguished name

SYNOPSIS
       #include <gnutls/x509.h>

       int  gnutls_x509_crt_get_dn_by_oid(gnutls_x509_crt_t  cert,  const  char  *  oid,  int  indx,  unsigned	int raw_flag, void * buf, size_t *
       sizeof_buf);

ARGUMENTS
       gnutls_x509_crt_t cert
		   should contain a gnutls_x509_crt_t structure

       const char * oid
		   holds an Object Identified in null terminated string

       int indx    In case multiple same OIDs exist in the RDN, this specifies which to send. Use zero to get the first one.

       unsigned int raw_flag
		   If non zero returns the raw DER data of the DN part.

       void * buf  a pointer where the DN part will be copied (may be null).

       size_t * sizeof_buf
		   initially holds the size of buf

DESCRIPTION
       This function will extract the part of the name of the Certificate subject specified by the given OID. The output, if the raw flag  is  not
       used, will be encoded as described in RFC2253. Thus a string that is ASCII or UTF-8 encoded, depending on the certificate data.

       Some  helper macros with popular OIDs can be found in gnutls/x509.h If raw flag is zero, this function will only return known OIDs as text.
       Other OIDs will be DER encoded, as described in RFC2253 -- in hex format with a 'using gnutls_x509_dn_oid_known().

       If buf is null then only the size will be filled.

RETURNS
       GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long enough, and in that case the *sizeof_buf will be updated with the  required
       size.  On success 0 is returned.
