What are some better ways to avoid the do-while(0); hack in C++?
...mit code: all operations succeeded
*r = computed_value_n;
cleanup:
free_resource1(r1);
free_resource2(r2);
return result;
}
In C, in most codebases, the if(error_ok != ... and goto code is usually hidden behind some convenience macros (RET(computation_result), ENSURE_SUCCESS(comput...
What's so wrong about using GC.Collect()?
...or. (e.g. I don't care if it's Windows, Mac, or Linux: when I'm allocating/freeing memory in C/C++ it's new/delete malloc/dealloc). I could always be wrong so feel free to correct me.

[精华] VC中BSTR、Char和CString类型的转换 - C/C++ - 清泛网 - 专注C/C++及内核技术
...;
char* lpszText2 = _com_util::ConvertBSTRToString(bstrText);
SysFreeString(bstrText); // 用完释放
delete[] lpszText2;
return 0;
}
方法二，使用_bstr_t的赋值运算符重载。例如：
_bstr_t b = bstrText;
char* lpszText2 = b;

When should I use Inline vs. External Javascript?
...other connection(s) and delay execution. Since this execution is basically free (as the server side is talking to the database) it must be clear that all of these jumps would cost more than doing no jumps at all. If there were a browser quirk that said external js executes faster we could measure wh...

(Note: Use exec python -c ... to replace the current shell, this frees one PID. The solution can be improved with some IO redirection as well, freeing unused FDs. This is up to you.)
How this works (I think): ctypes.CDLL(None) loads the standard C library and runs the pause() function i...
Why is SCTP not much used/known
...plication using TCP for non-transient connections implements, is there for free.
My personal summary of SCTP is that it doesn't do anything you couldn't do another way (in TCP or UDP) with substantial application support. The thing it provides is the ability to not have to implement that code (bad...
Why does this C++ snippet compile (non-void function does not return a value) [duplicate]
...ndard does not require this to generate an error.
So compiler vendors are free to generate a warning if they are quite sure that a function is missing a return and the user is then free to ignore/mask that warning in those rare cases where the compiler was actually wrong.
