No, that won't work - it'll break as soon as I test it for example.

You can just set that param to null. The man page says:

publickey - Path name of the public key file. (e.g.
/etc/ssh/hostkey.pub). If libssh2 is built against OpenSSL, this
option can be set to NULL.

(note that libssh2_userauth_publickey_fromfile is just a macro over
libssh2_userauth_publickey_fromfile_ex)
