c – 如何获取执行程序的人的用户名？

GetUserName()

例：

char user_name[UNLEN+1];
 DWORD user_name_size = sizeof(user_name);
 if (GetUserName(user_name,&user_name_size))
     cout << "Your user name is: " << user_name << endl;
 else
     /* Handle error */

Linux的

看看getpwuid：

The getpwuid() function shall search
the user database for an entry with a
matching uid.

The getpwuid() function shall return a
pointer to a struct passwd

struct passwd将包含char * pw_name.

使用getuid获取用户标识.
