Look into CreateMutex() for windows systems.

//declaring section as read/write/shared
#pragma comment(linker, "/section:SomeSectionName,rws&quot

#pragma data_seg("SomeSectionName&quot//begin of section
//the section there will be shared
//between different instances of programs

static bool isRunningAlready = false;

#pragma data_seg() //end iof section

int main()
{
if(isRunningAlready)return 0;
isRunningAlready = true;
......
return 0;
}
