<p>
<h2 >DESCRIPTION</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 >size_t userid() const</strong>:<br/>
        Returns the user's user-id.

<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>

<p>
<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.
