# libssh2\_keepalive\_config(3)

short function description

## NAME

libssh2\_keepalive\_config - short function description

## SYNOPSIS

```
#include <libssh2.h>
void
libssh2_keepalive_config(LIBSSH2_SESSION *session,
                         int want_reply,
                         unsigned int interval);
```

## 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)](/libssh2_keepalive_send/3.md)**.

## RETURN VALUE

Nothing

## AVAILABILITY

Added in libssh2 1.2.5
