## Detailed Description

### template<class T>
class KUser< T >

Represents a user on your system.

This class represents a user on your system. You can either get information about the current user, of fetch information about a user on the system. Instances of this class will be explicitly shared, so copying objects is very cheap and you can safely pass objects by value.

## Member Enumeration Documentation

template<class T>
enum KUser::UIDMode

  | Enumeration values:
  UseEffectiveUID | Use the effective user id.
  UseRealUserID | Use the real user id.
Definition at line 49 of file kuser.h.

## Constructor & Destructor Documentation

template<class T>
KUser< T >::KUser | ( | UIDMode | mode = `UseEffectiveUID` | ) |

  | Creates an object that contains information about the current user. (as returned by getuid(2) or geteuid(2), taking $LOGNAME/$USER into account). Parameters:
  | mode | if UseEffectiveUID is passed the effective user is returned. If UseRealUserID is passed the real user will be returned. The real UID will be different than the effective UID in setuid programs; in such a case use the effective UID for checking permissions, and the real UID for displaying information about the user.
Definition at line 68 of file kuser.cpp. References KUser< T >::uid(), and KUser< T >::UseEffectiveUID. Referenced by KUser< T >::allUsers().

template<class T>
KUser< T >::KUser | ( | long | uid | ) |

  | Creates an object for the user with the given user id. If the user does not exist isValid() will return false. Parameters:
  | uid | the user id
Definition at line 82 of file kuser.cpp.

template<class T>
KUser< T >::KUser | ( | const QString & | name | ) |

  | Creates an object that contains information about the user with the given name. If the user does not exist isValid() will return false. Parameters:
  | name | the name of the user
Definition at line 86 of file kuser.cpp.

template<class T>
KUser< T >::KUser | ( | const char * | name | ) |

  | Creates an object that contains information about the user with the given name. If the user does not exist isValid() will return false. Parameters:
  | name | the name of the user
Definition at line 90 of file kuser.cpp.

template<class T>
KUser< T >::KUser | ( | struct passwd * | p | ) |

  | Creates an object from a passwd structure. If the pointer is null isValid() will return false. Parameters:
  | p | the passwd structure to create the user from
Definition at line 94 of file kuser.cpp.

template<class T>
KUser< T >::KUser | ( | const KUser< T > & | user | ) |

  | Creates an object from another KUser object. Parameters:
  | user | the user to create the new object from
Definition at line 98 of file kuser.cpp.
