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"); }
Do you have....

Hi,
How do you measure the memory usage of an application or process in Linux? I've read here that "ps" is not an accurate tool to use for this intent.
Thanks, Kenneth

ngrep -d any -W byline port 80

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.
