Variable Documentation

BoolValues

const char* BoolValues[]

Initial value:

= {
  "no", "yes", "n", "y", "false", "true", "0", "1", "off", "on", NULL,
}

Valid strings for creating a Bool.

These strings are case-insensitive.

CstBool

const struct ConfigSetType CstBool

Initial value:

= {
  DT_BOOL,
  "boolean",
  bool_string_set,
  bool_string_get,
  bool_native_set,
  bool_native_get,
  NULL, 
  NULL, 
  bool_reset,
  NULL, 
}
