What's the return value of IL_LOADFUNC?

[chenlee]

From il_register.c, IL_LOADFUNC should return IL_NO_ERROR if no error occured.

But in documentation, IL_LOADFUNC returns IL_TRUE if no error. And many file loading functions in DevIL 1.6.5 source codes do this wrong thing.

[chenlee]

Codes from il_register.c :

ILboolean iRegisterLoad(const ILstring FileName)
{
    ...
   

    Error = TempNode->Load(FileName);
    if (Error == IL_NO_ERROR || Error == 0) {  // 0 and IL_NO_ERROR are both valid.
        return IL_TRUE;
    }
    else {
        ilSetError(Error);
        return IL_FALSE;
    }
        }
        TempNode = TempNode->Next;
    }
   
    ...
}

==============
should it be :

if ( Error == IL_NO_ERROR || Error == IL_TRUE )
{
...
}

There are several inconsistencies like this.  I would just recommend using whatever works for you.  It's not about to be changed on you.
