◆ run()

static void run ( void *  cls,
char *const *  args,
const char *  cfgfile,
const struct GNUNET_CONFIGURATION_Handle cfg

static

Print each option in a given section.

Main task to run to perform operations typical for gnunet-config as per the configuration settings given in cls.

Parameters
clsclosure with the struct GNUNET_CONFIGURATION_ConfigSettings
argsremaining command-line arguments
cfgfilename of the configuration file used (for saving, can be NULL!)
