// InitializeDLL
// Purpose:
// This function gets called when the DLL first gets loaded. It will only be called once (until the
// DLL is unloaded). Passed in is a struct of data passed from the game needed for the DLL to interact
// with D3. Usually this function will just call osicommon_Initialize(), which sets up the imported
// functions. However, you can alloc some memory or whatever in this function, and free it in ShutdownDLL().
// Note: You cannot call any imported functions until osicommon_Initialize() is called.
// Returns 1 if initialization went ok, 0 if there was an error and the DLL should not be loaded.

// ShutdownDLL
// Purpose:
// This function is called right before a DLL is about to be unloaded from memory. You can free
// any unfree'd memory, or anything else you need to do. Don't worry about destroying any instances
// of scripts, as they will all be automatically destroyed before this function is called. The
// same goes for any memory allocated with Scrpt_MemAlloc(), as this will automatically be freed
// when a scripts instance is destroyed.
void STDCALL ShutdownDLL(void) {}
// GetGOScriptID
// Purpose:
// Given the name of the object (from it's pagename), this function will search through it's
// list of General Object Scripts for a script with a matching name (to see if there is a script
// for that type/id of object within this DLL). If a matching scriptname is found, a UNIQUE ID
// is to be returned back to Descent 3. This ID will be used from here on out for all future
// interaction with the DLL. Since doors are not part of the generic object's, it's possible
// for a door to have the same name as a generic object (OBJ_POWERUP, OBJ_BUILDING, OBJ_CLUTTER
// or OBJ_ROBOT), therefore, a 1 is passed in for isdoor if the given object name refers to a
// door, else it is a 0. The return value is the unique identifier, else -1 if the script
// does not exist in the DLL.

// Purpose:

// particular script (by allocating and initializing memory, etc.). A pointer to this instance
// is to be returned back to Descent 3. This pointer will be passed around, along with the ID

// Purpose:

// passes the event to that instance of the script to be handled. Return a combination of
// CONTINUE_CHAIN and CONTINUE_DEFAULT, to give instructions on what to do based on the
// event. CONTINUE_CHAIN means to continue through the chain of scripts (custom script, level
// script, mission script, and finally default script). If CONTINUE_CHAIN is not specified,
// than the chain is broken and those scripts of lower priority will never get the event. Return
// CONTINUE_DEFAULT in order to tell D3 if you want process the normal action that is built into
// the game for that event. This only pertains to certain events. If the chain continues
// after this script, than the CONTINUE_DEFAULT setting will be overridden by lower priority
// scripts return value.

// Purpose:
// This function is called when Descent 3 is saving or restoring the game state. In this function
// you should save/restore any global data that you want preserved through load/save (which includes
// demos). You must be very careful with this function, corrupting the file (reading or writing too
// much or too little) may be hazardous to the game (possibly making it impossible to restore the
// state). It would be best to use version information to keep older versions of saved states still
// able to be used. IT IS VERY IMPORTANT WHEN SAVING THE STATE TO RETURN THE NUMBER OF _BYTES_ WROTE
// TO THE FILE. When restoring the data, the return value is ignored. saving_state is 1 when you should
// write data to the file_ptr, 0 when you should read in the data.
