Detailed Description

The remote control utility contacts the unbound server over ssl and sends the command, receives the answer, and displays the result from the commandline.

Function Documentation

◆ usage()

static void usage ( void  )
static

timeout to wait for connection over stream, in msec

Give unbound-control usage, and exit (1).

Referenced by main().

◆ check_args_for_listcmd()

static void check_args_for_listcmd ( int  argc,
char *  argv[] 
)
static

check args, to see if too many args.

Because when a file is sent it would wait for the terminal, and we can check for too many arguments, eg. user put arguments on the commandline.
