ssh2_keepalive_send — Send a keepalive message
Sends a keepalive message on the given session,
according to the configuration set with
ssh2_keepalive_config().
Bilginize:
This function is only available when the extension is built against a libssh2 version providing keepalive support.
sessionAn SSH connection link identifier, obtained from a call to ssh2_connect().
Returns the number of seconds that may pass before another keepalive message
must be sent, or false on failure. 0 is returned when
keepalive messages are disabled.
Since 0 and false are both falsy, the
=== operator has to be used to tell them apart.
