Detailed Description

Definitions for global variables and associated functions.

Todo:: Many of these variables really belong to specific modules, and can also be made non-global.

Function Documentation

◆ clear_globals()

void clear_globals ( )

sets all global variables to default values

Todo:: Can these just be initialized at declaration? Especially if they are all moved to more appropriate modules.

◆ get_globals()

Globals* get_globals ( )

returns a pointer to the local Globals object

Store the pointer in a static variable for faster lookup

Variable Documentation

◆ g_tw_rng_default

unsigned g_tw_rng_default

Todo:: documentation needed
