rec_sighup()

static void rec_sighup ( int  i )

SIGHUP handler. SIGHUP handlers on daemons typically make them reread the config files and reinitialize itself. This behaviour is better left for an explicit shutdown and restart with Crossfire, as there is just too much persistent runtime state. However, another function of SIGHUP handlers is to reopen the log file for logrotate's benefit. We can do that here.

Parameters

i

options

struct Command_Line_Options options[]

static

Actual valid command line options. The way this system works is pretty simple - parse_args takes the options passed to the program and a pass number. If an option matches both in name and in pass (and we have enough options), we call the associated function. This makes writing a multi pass system very easy, and it is very easy to add in new options.
