NAME

       remctl_noop - Send a NOOP message to a remctl server

SYNOPSIS

       #include <remctl.h>

       int remctl_noop(struct remctl *r);

DESCRIPTION

       remctl_noop() sends a NOOP message to a remctl server and reads the expected NOOP response.  This is primarily used to keep a connection to
       a remctl server alive, such as through a firewall with a session timeout, while waiting to issue further commands.

       The NOOP message requires protocol version 3 support in the server, so the caller should be prepared for this function to fail, indicating
       that the connection could not be kept alive and possibly that it was closed by the server.  In this case, the client will need to
       explicitly reopen the connection with remctl_open().

RETURN VALUE

       remctl_noop() returns true on success and false on failure.  On failure, the caller should call remctl_error() to retrieve the error
       message.  In addition to network errors, this function may fail if the server doesn't support protocol version 3.
