Like -D_TS_ERRNO for thread-safe errno, but no such flag is needed on Linux.)
Does it give you any meaningful error message if you call it like this?
if (stat("file", &stat_obj) == -1) { perror("stat"); }

I want an easy way to create multiple directories in C++/Linux.
For example I want to save a file lola.file in the directory:
/tmp/a/b/c
but if the directories are not there I want them to be created automagically. A working example would be perfect.

Status:
mkdir -p /tmp/a/{b,c}/d
Will create the following paths:
/tmp/a/b/d /tmp/a/c/d
The braces allow you; #include "sysstat....
#include <sys/types.h> #include <sys/stat.h> int status; ...
But will work under Linux.

I need to keep statistics of daily network traffic for a linux machine (CentOS 5).
Is there a way to do it using standard/native tools or utilities?
Or do I have to dowload special software for that?
Thanks.

In Windows/DOS, I can say rename myfile.* yourfile.* to change the name but keep the extension. How is that accomplished on Linux?
The man page only suggests how to change the extension, but that's the opposite of what I want.
