asBSTR and bstr
Author
I'm having trouble making my script file read a *bstr from my host program.
I define the bstr like so:
asBSTR *timeStr;
I register the bstr like so:
r = engine->RegisterObjectProperty("CGame", "bstr timeStr", offsetof(CGame, timeStr)); assert( r >= 0 );
Then I have a function that returns a Time String:
Then every frame I make game.timeStr = TimeString(); inside of my host. When the player dies I want a script file to print the time that he played. So I do this:
bstr s = "Time: ";
s += game.timeStr;
And it crashes my progam. Any advice?
Here's an example of how I am returning bstr to script code. At least this doesn't crash, hopefully this is correct regarding memory usage as well.
static asBSTR script_Object_getName(Object *o){ char *name = o->getName(); asBSTR res = asBStrAlloc(strlen(name)); strcpy((char *)res, name); return res;}
The problem is the bstr has an extra dword at the start with the size of the string. You have to use BstrAlloc() to create an asBSTR
