# FBB::User(3bobcat)

## /etc/passwd user info
(libbobcat-dev_6.14.00)

## 2005-2026

## NAME

FBB::User - Provides the /etc/passwd info of the current user

## SYNOPSIS

#include <bobcat/user>
Linking option: -lbobcat

## DESCRIPTION

This class retrieves the information of the current user from the information in /etc/passwd. The class is a simple wrapper class around the getpwent(3) function.

## NAMESPACE

FBB
All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB.

## INHERITS FROM

-

## CONSTRUCTORS

- User():
  The default constructor determines the current user's data. This constructor throws an Exception exception if it did not properly complete because the current user name could not be found in /etc/passwd.

- User(size_t uid):
  The data of the user whose user-id is uid are determined. If the data could not be found an Exception is thrown.

- User(std::string const &name):
  The data of the user whose user-name is name are determined. If the data could not be found an Exception is thrown.

Copy and move constructors (and assignment operators) are available.

## MEMBER FUNCTIONS

- size_t eGroupid() const:
  Returns the user's effective group-id.
- size_t eUserid() const:
  Returns the user's effective user-id.
- size_t groupid() const:
  Returns the user's group-id.
- std::string homedir() const:
  Returns the user's home directory (including a trailing /).
- bool inGroup(size_t gid, bool useEffective = true) const:
  Returns true if the current user is a member of group gid, otherwise false is returned. The user's effective group id is also checked if useEffective is specified as true (which is provided as default function argument).
- std::string name() const:
  Returns the user's user-name.
- std::string password() const:
  Returns the user's encrypted password. But see also the BUGS section.
- std::string realname() const:
  Returns the user's real name, as listed in the /etc/passwd's gecos field.
- std::string shell() const:
  Returns the user's shell.
- size_t userid() const:
  Returns the user's user-id.

## EXAMPLE

    #include <bobcat/user>
    #include <iostream>

    using namespace std;
    using namespace FBB;

    int main()
    {
        User  user;

        cout << "\n"
            "name       : " << user.name()      << "\n" <<
            "password   : " << user.password()  << "\n" <<
            "user id    : " << user.userid()    << "\n" <<
            "group id   : " << user.groupid()   << "\n" <<
            "real name  : " << user.realname()  << "\n" <<
            "home dir   : " << user.homedir()   << "\n" <<
            "shell      : " << user.shell()     << "\n" << endl;
    }

## SEE ALSO

bobcat(7), getpwent(3)

## BUGS

If the user is a member of multiple groups, only the group id listed in /etc/passwd is returned by groupid().

If shadow passwording is used, the string returned by password() will probably not contain the encrypted password.
