in Linux you can also use the following using Posix library to retrieve the real user that owns the process: getuid() returns the real user ID of the calling process. see getuid man page

#include 
string userName = "unknownUser";
// Structure to store user info
struct passwd p;
// Get user ID of the application
uid_t uid = getuid();

// Buffer that contains password additional information
char pwdBuffer[ourPwdBufferSize];
// Temporary structure for reentrant function
struct passwd* tempPwdPtr;

if ((getpwuid_r(uid, &p, pwdBuffer, sizeof(pwdBuffer),
        &tempPwdPtr)) == 0) {
    userName = p.pw_name;
}
