you could use the following code to get the Username.

    #include 

    void main(void)
    {
        //following gets the appdata folder
        char szAppData[1024];
        char * szBufer      = 0;
        szBufer = getenv ("APPDATA");
        if (szBufer != NULL)
        {
           strcpy(szBufer , szAppData);
        }

        //following code gets the user name
        char szOSUserName[1024];
        szBufer = getenv ("USERNAME");
        if (szBufer != NULL)
        {
            strcpy(szBufer , szOSUserName);
        }
    }
