REMCTL_NOOP(3)						     remctl Library Reference						    REMCTL_NOOP(3)

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.

NAME

       remctl_set_timeout - Set timeout for subsequent remctl client operations

SYNOPSIS

       #include <remctl.h>

       int remctl_set_timeout(struct remctl *r, time_t timeout);

DESCRIPTION

       remctl_set_timeout() sets the timeout for connections and commands to timeout, which should be an integer number of seconds.  timeout may
       be 0 to clear a timeout that was previously set and restore the default behavior of having no timeout.  All subsequent operations on the
       given struct remctl argument will be subject to this timeout, including remctl_open() if called prior to calling remctl_open().

       The timeout is a timeout on network activity from the server, not on a complete operation.  So, for example, a timeout of ten seconds just
       requires that the server send some data every ten seconds.  If the server sends only tiny amounts of data at a time, the complete operation
       could take much longer than ten seconds without triggering the timeout.

RETURN VALUE

       remctl_set_timeout() returns true on success and false on failure.  The only failure case is if timeout is negative.  On failure, the
       caller should call remctl_error() to retrieve the error message.
