Enumeration Type Documentation

enum FileSlots
Enumerator:
CONFIG_SLOT 

Slot used for the GRF scanning and such.

This slot cannot be reused as it will otherwise cause issues when pressing "rescan directories". It can furthermore not be larger than LAST_GRF_SLOT as that complicates the testing for "too much NewGRFs".

SOUND_SLOT 

Slot for the sound.

FIRST_GRF_SLOT 

First slot usable for (New)GRFs used during the game.

LAST_GRF_SLOT 

Last slot usable for (New)GRFs used during the game.

MAX_FILE_SLOTS 

Maximum number of slots.

Definition at line 82 of file fios.h.

enum FileType

The different types of files that the system knows about.

Enumerator:
FT_NONE 

nothing to do

FT_SAVEGAME 

old or new savegame

FT_SCENARIO 

old or new scenario

FT_HEIGHTMAP 

heightmap file

Definition at line 111 of file fios.h.

Mode of the file dialogue window.

Enumerator:
SLD_LOAD_GAME 

Load a game.

SLD_LOAD_SCENARIO 

Load a scenario.

SLD_SAVE_GAME 

Save a game.

SLD_SAVE_SCENARIO 

Save a scenario.

SLD_LOAD_HEIGHTMAP 

Load a heightmap.

SLD_SAVE_HEIGHTMAP 

Save a heightmap.

Used with sort when sorting the file list.

Parameters
daA pointer to the first FiosItem to compare.
dbA pointer to the second FiosItem to compare.
Returns
-1, 0 or 1, depending on how the two items should be sorted.
