}
}
}

return _res;
}
void main()
{
// logS("-------------------------------------------------");
int i = 0;
if(true)
{
int _var = 12;
var _x = 2.1;
char* str = "come one man did you see face?";
int a[4];
a[0] = &_var;
a[1] = &_var;
a[2] = &_x;
a[3] = str;
STRING* s = Print(" %d*%d*%f,%s",a);
Print(" %d*%d*%f,%s",a);
//log(s);//data output by socket...
printf("%s",s->chars);
}
}
any one have good ideas for create dynamic parameter

I can't tell you why it doesn't crash the first time, although it should, but I can tell you that this won't work:
STRING* _str = "#1";
STRING* _res = "";
The reason is that you doesn't set _str and _res to new STRING pointers, but to a static char array. Use str_create() and later ptr_remove() to create and later remove your STRING. Also, it highly looks you are trying to reinvent the wheel here, if you just want a STRING containing the printf stuff, you can use something like this:
char temp[1024];
sprintf(temp, "%d*%d*%f,%s", _var, _var, _x, str);
log(_str(temp));
