Howto use libgrcypt for signature?

I'm writing a fuse fs for sftp, and using libgcrypt for encryption,
hmac, digest and dh.
Now I m working on the checking of the signature of H send by the
sender. The client creates also H,
and has to check the signature of H using the public key.
I've got the signature of H from the server, H and the public hostkey
of the server as string (length, buffer).
How to go futher? I know I have to use the function gcry_pk_verify, but how?
Do I have to convert the strings to some s-expressions using a format first?
Thanks in advance,
