[mbed-tls] signature verification of ECC type

Hello, we are using mbedTLS version 2.16. We are facing a problem in verifying the signed message for ECDSA type of algorithms. Do you have any sample code for this as given for the RSA type algorithm in rsa_verify.c.

We have derived the R and S values and their length, but we are not sure which context to use to verify the signature.

Please help urgently.
