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 LIB-
SSH2_ERROR_EAGAIN when it would otherwise block. While LIB-
SSH2_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 sup-
ported.
