<h1>C/C++ search</h1>
|
|
|
|
<p>You can conduct a fully or partially qualified name search. Further
|
|
qualifying a search increases the accuracy and relevance of search results. The
|
|
sections below provide guidance on how to control the scope of your search
|
|
through the use of search delimiters, correct syntax, and wildcards.</p>
|
|
|
|
<p>You can search for:<br>
|
|
<ul>
|
|
<li>language constructs within:
|
|
<ul>
|
|
<li>projects in your workspace</li>
|
|
<li>selected resources from various views</li>
|
|
<li>working sets</li>
|
|
</ul></li>
|
|
<li>a working set for references to particular elements</li>
|
|
<li>declarations of particular elements</li>
|
|
<li>definitions of particular elements</li>
|
|
<li>references of particular elements</li>
|
|
</ul>
|
|
</p>
|
|
|

<h2>What you can search for</h2>
|
|
<p>The table below lists the element types that you can search for and special
|
|
considerations to note when searching for a given element type. You can search
|
|
for some or all of the element types matching a search string that you
|
|
specify. If you choose to search for matching elements, all types, macros, and typdefs are included in the search.</p>

the search by specifying "class" or "struct" in front of the name

search for anonymous classes and structures.</td>

<h2>How you can limit your search</h2>
|
|
|
|
<p>You can limit your search to one or all of the following:</p>
|
|
|
|
<ul>
|
|
<li>Declarations</li>
|
|
<li>References</li>
|
|
<li>Definitions (for functions, methods, variables and fields)</li>
|
|
</ul>
|
|
|
|
<p>You can control the scope of the search by specifying which of the following
|
|
is to be searched:</p>
|
|
<ul>
|
|
<li>Workspace</li>
|
|
<li>Working Set</li>
|
|
<li>Selected Resources</li>
|
|
</ul>
|
|
|
|
<h2>Wildcard characters</h2>
|
|
<p>You can use wildcard characters to further refine your search.</p>
|
|

<!-- no support for function parameters
|
|
<p><strong>Tip: </strong>Do not use wild cards between the brackets of a function or
|
|
method pattern. For example, the search
|
|
string <samp>f( * )</samp> is an invalid search that results in a search for any function <samp>f</samp>
|
|
because
|
|
the asterisk is interpreted as a pointer rather than a wild card.</p>

<h2>Search results</h2>
|
|
<p>Search results are displayed in the Search view. You can sort your search by Name, Parent Name and Path. You can also repeat
|
|
your last search.</p>
|
|
|
|
<h2>Search Concepts</h2>
|
|
|
|
<h3>Declarations</h3>
|
|
<p>According to the ANSI C++ Spec, a declaration is a statement that <Q>introduces a name into a translation unit or re-declares a name that has been previously introduced by a previous declaration</Q>.</p>
|
|
<p>All C/C++ search elements can be searched for declarations.</p>
|
|
|
|
<h3>Definitions</h3>
|
|
<p>Most declarations are also definitions; in other words, they also define the entity for they declare the name for. However there are some elements that can have separate definitions from their declarations.</p>
|
|
<p>For C/C++ search the following elements can be searched for definitions:
|
|
<ul>
|
|
<li>Functions/Methods - the definition is where the code implementation resides</li>
|
|
<li>Variable:
|
|
<ol>
|
|
<li>Extern - the definition is where the variable is initialized</li>
|
|
<li>Non extern - the definition of a variable is where it is declared </li>
|
|
</ol></li>
|
|
<li>Field:
|
|
<ol>
|
|
<li>Static fields - the definition of a static field is where it gets initialized</li>
|
|
<li>Non static fields - the definition corresponds to the fields declaration</li>
|
|
</ol></li>
|
|
<li>Namespace - the definition of a namespace is the same as its declaration</li>
|
|
</ul></p>
|
|
|
|
<h3>References</h3>
|
|
<p>By selecting references, C/C++ search will return all of the places the selected element is used.</p>
|
|
|
|
<h3>All Occurrences</h3>
|
|
<p>Selecting 'All Occurrences' in the Limit To section will result in a search for declarations, definitions (if applicable) and references for whatever element or elements have been selected.</p>
|
|
|
|
<h3>Any Element</h3>
|
|
<p>Selecting 'Any Element' in the Search For section will result in a search for all of the listed elements plus macros and typedefs.</p>
