<p>
        A structure used to maintain the state of a traversal.

<div class="ulist"><ul>

current tree. If this is the top-level tree <code>prev</code> will point to
a dummy traverse_info.

<p>
<code>name</code> is the entry for the current tree (if the tree is a subtree).

<code>fn</code> is a callback called for each entry in the tree. See Traversing for more
information.

        Initialize a <code>tree_desc</code> and decode its first entry. The buffer and

        members of <code>struct tree</code>.

<p>
        Initialize a <code>tree_desc</code> and decode its first entry given the sha1 of
        a tree. Returns the <code>buffer</code> member if the sha1 is a valid tree
        identifier and NULL otherwise.

<p>
        Initialize a <code>traverse_info</code> given the pathname of the tree to start
        traversing from. The <code>base</code> argument is assumed to be the <code>path</code>
        member of the <code>name_entry</code> being recursed into unless the tree is a
        top-level tree in which case the empty string ("") is used.

<dd>
<p>
        Visit the next entry in a tree. Returns 1 when there are more entries
        left to visit and 0 when all entries have been visited. This is
        commonly used in the test of a while loop.
</p>
</dd>
<dt class="hdlist1">
<code>tree_entry_len</code>
</dt>
<dd>
<p>
        Calculate the length of a tree entry&#8217;s pathname. This utilizes the
        memory structure of a tree entry to avoid the overhead of using a
        generic strlen().
</p>
</dd>
<dt class="hdlist1">
<code>update_tree_entry</code>
</dt>
<dd>
<p>
        Walk to the next entry in a tree. This is commonly used in conjunction

</p>
</dd>
<dt class="hdlist1">
<code>tree_entry_extract</code>
</dt>
<dd>

        Decode the entry currently being visited (the one pointed to by
        <code>tree_desc's</code> <code>entry</code> member) and return the sha1 of the entry. The
        <code>pathp</code> and <code>modep</code> arguments are set to the entry&#8217;s pathname and mode
        respectively.
</p>
</dd>
<dt class="hdlist1">
<code>get_tree_entry</code>
</dt>

<p>
        Find an entry in a tree given a pathname and the sha1 of a tree to
        search. Returns 0 if the entry is found and -1 otherwise. The third
        and fourth parameters are set to the entry&#8217;s sha1 and mode

<dd>
<p>
        Traverse <code>n</code> number of trees in parallel. The <code>fn</code> callback member of
        <code>traverse_info</code> is called once for each tree entry.
</p>
</dd>
<dt class="hdlist1">

        The arguments passed to the traverse callback are as follows:

<code>n</code> counts the number of trees being traversed.

<li>
<p>
<code>dirmask</code> has its nth bit set if the nth tree&#8217;s entry is a directory.
</p>
</li>
<li>
<p>
<code>entry</code> is an array of size <code>n</code> where the nth entry is from the nth tree.
</p>
</li>
<li>
<p>
<code>info</code> maintains the state of the traversal.
</p>
</li>
</ul></div>
<div class="paragraph"><p>Returning a negative value will terminate the traversal. Otherwise the
return value is treated as an update mask. If the nth bit is set the nth tree
will be updated and if the bit is not set the nth tree entry will be the
same in the next callback invocation.</p></div>
</dd>
<dt class="hdlist1">
<code>make_traverse_path</code>
</dt>
<dd>
<p>
        Generate the full pathname of a tree entry based from the root of the
        traversal. For example, if the traversal has recursed into another
        tree named "bar" the pathname of an entry "baz" in the "bar"
        tree would be "bar/baz".
</p>
</dd>
<dt class="hdlist1">
<code>traverse_path_len</code>
</dt>
<dd>
<p>
        Calculate the length of a pathname returned by <code>make_traverse_path</code>.
