Detailed Description

The config checker checks for syntax and other errors in the unbound.conf file, and can be used to check for errors before the server is started or sigHUPped.

Exit status 1 means an error.

Function Documentation

static void usage

(

void

)

[static]

Give checkconf usage, and exit (1).

static void print_option	(	struct config_file *	cfg,
		const char *	opt
	)			[static]

Print given option to stdout.

Parameters:

	cfg,:	config
	opt,:	option name without trailing :. This is different from config_set_option.
