Gib mir die Anzahl der CPU-Kerne:

getCPUCores.c

#include <stdio.h>
#include <unistd.h>
//----------------------------------------------
int GetCores(void)
{
	return  sysconf( _SC_NPROCESSORS_ONLN );
}
//----------------------------------------------
void main(void)
{
	printf ("Cores: %d \n",GetCores());
return;
}
