NAME
       gnutls_decode_gost_rs_value - API function

SYNOPSIS
       #include <gnutls/crypto.h>

       int gnutls_decode_gost_rs_value(const gnutls_datum_t * sig_value,
       gnutls_datum_t * r, gnutls_datum_t * s);

ARGUMENTS
       const gnutls_datum_t * sig_value
                   will holds a GOST signature according to RFC 4491 section

                   will contain the r value

       gnutls_datum_t * s
                   will contain the s value

DESCRIPTION
       This function will decode the provided  sig_value , into  r and  s
       elements.  See RFC 4491 section 2.2.2 for the format of signature value.

       being interpreted as negative values. The value should be deallocated
       using gnutls_free().

RETURNS
       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error code is
