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.

The copy and move constructors are available.

OVERLOADED OPERATORS

The copy and move 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;
}

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.
