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  isn't  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.
