NAME
       libssh2_session_method_pref - set preferred key exchange method

SYNOPSIS
       #include <libssh2.h>

       int
       libssh2_session_method_pref(LIBSSH2_SESSION *session,
                                   int method_type, const char *prefs);

DESCRIPTION
       session - Session instance as returned by libssh2_session_init_ex(3)

       method_type - One of the Method Type constants.

       prefs - Coma delimited list of preferred methods to use with the most
       preferred listed first and the least preferred listed last.  If a
       method is listed which is not supported by libssh2 it will be ignored
       and not sent to the remote host during protocol negotiation.

       Set preferred methods to be negotiated. These preferences must be set
       prior to calling libssh2_session_handshake(3) as they are used during
       the protocol initiation phase.

RETURN VALUE
       Return 0 on success or negative on failure.  It returns
       LIBSSH2_ERROR_EAGAIN when it would otherwise block. While
       LIBSSH2_ERROR_EAGAIN is a negative number, it is not really a failure
       per se.

ERRORS
       LIBSSH2_ERROR_INVAL - The requested method type was invalid.

       LIBSSH2_ERROR_ALLOC -  An internal memory allocation call failed.

       LIBSSH2_ERROR_METHOD_NOT_SUPPORTED - The requested method is not
       supported.
