NAME
       gnutls_decode_rs_value - API function

SYNOPSIS
       #include <gnutls/crypto.h>

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

ARGUMENTS
       const gnutls_datum_t * sig_value
                   holds a Dss-Sig-Value DER or BER encoded structure

       gnutls_datum_t * r
                   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. The Dss-Sig-Value is used for DSA and ECDSA signatures.

       The output values may be padded with a zero byte to prevent them from
       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
       returned.

SINCE
       3.6.0
