<h1>FBB::User(3bobcat)</h1>
<h2>libbobcat-dev_3.19.01-x.tar.gz /etc/passwd user info</h2>
<h2>2005-2013</h2>


<p>
<h2>NAME</h2>FBB::User - Provides the <em>/etc/passwd</em> info of the current user
<p>
<h2>SYNOPSIS</h2>
    <strong>#include &lt;bobcat/user&gt;</strong><br>
    Linking option: <em>-lbobcat</em> 
<p>
<h2>DESCRIPTION</h2>
    This class retrieves the information of the current user from the
information in <em>/etc/passwd</em>. The class is a simple wrapper class around the
<strong>getpwent</strong>(3) function.
<p>
<h2>NAMESPACE</h2>
    <strong>FBB</strong><br>
    All constructors, members, operators and manipulators, mentioned in this
man-page, are defined in the namespace <strong>FBB</strong>.
<p>
<h2>INHERITS FROM</h2>
    -
<p>
<h2>CONSTRUCTORS</h2>
    <ul>
    <li> <strong>User()</strong>:<br>
        The default constructor determines the current user's data.  
        This constructor throws an <em>Exception</em> exception if it did not properly
complete because the current user name could not be found in <em>/etc/passwd</em>.
    </ul>
    The copy and move constructors are available.
<p>
<h2>OVERLOADED OPERATORS</h2>
<p>
The copy and move assignment operators are available.
<p>
<h2>MEMBER FUNCTIONS</h2>
    <ul>
    <li> <strong>size_t eGroupid() const</strong>:<br>
        Returns the user's <em>effective</em> group-id.
    <li> <strong>size_t eUserid() const</strong>:<br>
        Returns the user's <em>effective</em> user-id.
    <li> <strong>size_t groupid() const</strong>:<br>
        Returns the user's group-id.
    <li> <strong>std::string homedir() const</strong>:<br>
        Returns the user's home directory (including a trailing <em>/</em>).
    <li> <strong>bool inGroup(size_t gid, bool useEffective = true) const</strong>:<br>
       Returns <em>true</em> if the current user is a member of group <em>gid</em>,
        otherwise <em>false</em> is returned. The user's effective group id is also
        checked if <em>useEffective</em> is specified as <em>true</em> (which is
        provided as default function argument).
    <li> <strong>std::string name() const</strong>:<br>
        Returns the user's user-name.
    <li> <strong>std::string password() const</strong>:<br>
        Returns the user's encrypted password. But see also the <strong>BUGS</strong> section. 
    <li> <strong>std::string realname() const</strong>:<br>
        Returns the user's real name, as listed in the <em>/etc/passwd</em>'s <em>gecos</em> field.
    <li> <strong>std::string shell() const</strong>:<br>
        Returns the user's shell.
    <li> <strong>size_t userid() const</strong>:<br>
        Returns the user's user-id.
    </ul>
<p>
<h2>EXAMPLE</h2>
    <pre>
#include &lt;bobcat/user&gt;
#include &lt;iostream&gt;

using namespace std;
using namespace FBB;

int main()
{
    User  user;

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

<h2>FILES</h2>
    <em>bobcat/user</em> - defines the class interface
<p>
<h2>SEE ALSO</h2>
    <strong>bobcat</strong>(7), <strong>getpwent</strong>(3)
<p>
<h2>BUGS</h2>
    If the user is a member of multiple groups, only the group id listed in
<em>/etc/passwd</em> is returned by <strong>groupid()</strong>.
<p>
If shadow passwording is used, the string returned by <strong>password()</strong> will
probably not contain the encrypted password.
