linux – Why sysinfo returns more processes than ps aux

Question:

Why sysinfo return more processes ( procs ) than ps aux

Function example:

static void
print_sysinfo()
{
 struct sysinfo info;
 sysinfo(&info);
 printf("Number of current processes - %d\n", info.procs); # На моей системе это 452
}

But when I ask for the output of a line-counting command in Linux it looks like this:

ps aux | wc -l # 179

What's the catch? The manual says Number of current processes . Why is it not the same as aux ? Now I'm a little confused about how many actually running processes are on my system …

Answer:

As andreymal pointed out, this is because threads count as processes, and ps aux does not display threads.
