# [SYNOPSIS](#SYNOPSIS)

```
#include <libssh2.h>
void
libssh2_keepalive_config(LIBSSH2_SESSION *session,


                         int want_reply,


                         unsigned int interval);
```

# [DESCRIPTION](#DESCRIPTION)

Set how often keepalive messages should be sent. **want\_reply** indicates whether the keepalive messages should request a response from the server. **interval** is number of seconds that can pass without any I/O, use 0 (the default) to disable keepalives. To avoid some busy-loop corner-cases, if you specify an interval of 1 it will be treated as 2.

Note that non-blocking applications are responsible for sending the keepalive messages using [**libssh2\_keepalive\_send(3)**](/man/os/libssh2/libssh2_keepalive_send.3).
