<em>baton</em> is provided by the caller, <em>path</em> is the pathname of the file in revision <em>rev</em> and <em>rev_props</em> are the revision properties.<p>
|
|
If <em>delta_handler</em> and <em>delta_baton</em> are non-NULL, they may be set to a handler/baton which will be called with the delta between the previous revision and this one after the return of this callback. They may be left as NULL/NULL.<p>
|
|
<em>result_of_merge</em> will be <code>TRUE</code> if the revision being returned was included as the result of a merge.<p>
|
|
<em>prop_diffs</em> is an array of <a class="el" href="structsvn__prop__t.html" title="A general in-memory representation of a single property.">svn_prop_t</a> elements indicating the property delta for this and the previous revision.<p>
|
|
<em>pool</em> may be used for temporary allocations, but you can't rely on objects allocated to live outside of this particular call and the immediately following calls to <em>*delta_handler</em> if any. (Pass in a pool via <em>baton</em> if need be.)<p>
