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 preferrences 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.
