<h2>libbobcat-dev_3.19.01-x.tar.gz Shared Memory Offsets</h2>
<h2>2005-2013</h2>


<p>
<h2>NAME</h2>FBB::Sharedpos - Shared Memory offset controller
<p>
<h2>SYNOPSIS</h2>
    <strong>#include &lt;bobcat/sharedpos&gt;</strong><br>
    Linking option: <em>-lbobcat</em> 
<p>
<h2>DESCRIPTION</h2>
<p>
The class <strong>SharedPos</strong> is a support class for Bobcat's shared memory
handling classes. It controls the shared memory read/write ofset and ensures
that shared memory operations never exceed the shared memory's maximum offset.
<p>
The class <strong>SharedPos</strong> has several public members, but they are primarily
useful for other <em>Shared*</em> classes offered by Bobcat. There is probably
little use for a stand-alone <strong>SharedPos</strong> object.
<p>
In the descriptions of the class's member functions <em>offset</em> refers to
the read/write offset within the available shared memory.
<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>TYPEDEFS AND ENUMS</h2>
<p>
<h2>CONSTRUCTORS</h2>
<p>
Default, copy and move constructors are available. The default constructor
        does not yet monitor the offsets for a shared memory segment. The
        member <em>reset</em> is used to start monitoring offsets.
<p>
<h2>OVERLOADED OPERATORS</h2>
    <ul>
    <li> <strong>void operator++()</strong>:<br> 
       The offset is incremented. If this member is called when the offset is
        equal to the shared memory's maximum offset an <em>FBB::Exception</em> is
        thrown.
<p>
<li> <strong>void operator+=(size_t len)</strong>:<br> 
       The offset is incremented by <em>len</em>. If <em>offset + len</em> exceeds the
        shared memory's maximum offset then the offset is set to the maximum
        offset and an <em>FBB::Exception</em> is thrown.
<p>
<li> <strong>std::ostream &amp;operator&lt;&lt;(std::ostream &amp;out, SharedPos const &amp;pos)</strong>:<br> 
       Inserts information about the <strong>FBB::SharedPos</strong> object into <em>out</em>.
    </ul>
<p>
The copy and move assignment operators are available.
<p>
<h2>MEMBER FUNCTIONS</h2>
<p>
<ul>
    <li> <strong>bool atMaxOffset() const</strong>:<br>
       Returns <em>true</em> if offset equals the maximum offset that can be used
        for the current shared memory segment.<br>
       The behavior of this member is undefined until <em>setup</em> has been
        called. 
<p>
<li> <strong>size_t blockIdx() const</strong>:<br>
       The index of the shared segment data block in which offset is located
        is returned. 
<p>
<li> <strong>size_t blockOffset() const</strong>:<br>
       The index within the shared segment data block matching offset is
        returned.  
<p>
<li> <strong>bool eof() const</strong>:<br>
       Returns <em>true</em> if offset exceeds the maximum offset of any character
        ever written to the shared memory pointed at by
        <em>sharedData</em>. If <em>eof</em> returns <em>true</em> information may still 
        be <em>written</em> to the shared memory: writting is possible until the
        maximum shared memory segment offset has been reached.<br>
       The behavior of this member is undefined until <em>setup</em> has been
        called. 
<p>
<li> <strong>std::streamsize eos() const</strong>:<br>
       The offset just beyond the maximum offset for the current shared
        segment data block is returned.<br>
       The behavior of this member is undefined until <em>setup</em> has been
        called. 
<p>
<li> <strong>std::streamsize maxOffset() const</strong>:<br>
       The maximum possible offset that can be used for the currently
        monitored shared memory segment is returned. Zero is returned until
        <em>setup</em> has been called.
<p>
<li> <strong>std::streamsize offset() const</strong>:<br>
       The offset within the currently monitored shared memory segment is
        returned. Zero is returned until <em>setup</em> has been called.
<p>
<li> <strong>void setup(SharedSegment *sharedData)</strong>:<br>
       The <em>SharedPos</em> object is reset to monitor the offset of a new
        <em>FBB::SharedSegment</em> object. The <em>SharedSegment *</em> must point to a
        <em>SharedSegment</em> segment (cf. <strong>sharedsegment</strong>(3bobcat)) that must exist
        until the end of the <strong>FBB::SharedPos</strong> object's lifetime or until the
        next <em>reset</em> call. Immediately after calling <em>reset</em> offset has
        the value 0. 
<p>
<li> <strong>std::streamsize showmanyc() const</strong>:<br>
       The number of characters that can be read from the current shared
        segment data block is returned.  This member interrogates the number
        of readable characters in the shared memory segment. This number may
        change while this member is being executed. In order to receive a
        stable return value, calling functions should have obtained a lock on
        the shared memory segment before calling this member. See also the
        <strong>sharedsegment</strong>(3bobcat) man-page.<br>
       The behavior of this member is undefined until <em>setup</em> has been
        called. 
<p>
<li> <strong>std::ios::pos_type seek(std::ios::off_type offset, 
                                std::ios::seekdir way = std::ios::beg)</strong>:<br>
       The monitored offset is changed to this member's <em>offset</em> argument,
        relative to <em>way</em>. Seeking beyond <em>eof</em> is OK; -1 is returned when
        seeking beyond <em>maxOffset</em> or seeking before the shared segment's
        offset 0.
    </ul>
