Thread: Hit a annoying bug with my buffer insertion

Never mind, found what I had been doing wrong, my dumbass self started the printf for the expected result but never finished it resulting in unexpected results, with a few fixes (both to the printf and how the values were used in the callbacks) I got it fixed:

Code:

pawd test_oust_paws( obj_paws *obj )
{
	obj->action = "oust from";
	if ( obj->ud )
	{
		pawd len = obj->leng;
		pawc *txt = obj->text;
		/* Leaving a fair bit of leeway */
		pawd need = (len * 2) + 8;
		pawc *old = (len >= 0) ? PawAllocObj( need ) : NULL;
		if ( old )
		{
			pawd err = -1;
			pawc *nxt = old + len + 1;
			pawd pos = abs(rand() % len);
			pawd rem = abs(rand() % (len - pos));
			pawc num = sprintf
				( nxt, "%.*s%s", pos, txt, txt + pos + rem );
			paw_cpy( old, txt, len );
			obj->oustCB( obj->ud, pos, NULL, rem );
			err = text_testall( obj, txt, nxt, num, old );
			if ( err )
			{
				printf
				(
					"Characters from positions %d to %d "
					"should've been removed, was '%.*s'\n",
					pos, pos + rem, rem, old + pos
				);
			}
			PawAlloc( old, 0 );
			return err;
		}
		puts("Couldn't allocate memory for temporary string");
		return -1;
	}
	printf("Object does not exist, cannot oust %s\n", obj->type );
	return -1;
}
