| <h4 class="subsubsection">23.3.3.13 Program Spaces In Guile</h4> |
| |
| <a name="index-progspaces-in-guile"></a> |
| <a name="index-_003cgdb_003aprogspace_003e"></a> |
| <p>A program space, or <em>progspace</em>, represents a symbolic view |
| of an address space. |
| It consists of all of the objfiles of the program. |
| See <a href="Objfiles-In-Guile.html#Objfiles-In-Guile">Objfiles In Guile</a>. |
| See <a href="Inferiors-and-Programs.html#Inferiors-and-Programs">program spaces</a>, for more details |
| about program spaces. |
| </p> |
| <p>Each progspace is represented by an instance of the <code><gdb:progspace></code> |
| smob. See <a href="GDB-Scheme-Data-Types.html#GDB-Scheme-Data-Types">GDB Scheme Data Types</a>. |
| </p> |
| <p>The following progspace-related functions are available in the |
| <code>(gdb)</code> module: |
| </p> |
| <dl> |
| <dt><a name="index-progspace_003f"></a>Scheme Procedure: <strong>progspace?</strong> <em>object</em></dt> |
| <dd><p>Return <code>#t</code> if <var>object</var> is a <code><gdb:progspace></code> object. |
| Otherwise return <code>#f</code>. |
| </p></dd></dl> |
| |
| <dl> |
| <dt><a name="index-progspace_002dvalid_003f"></a>Scheme Procedure: <strong>progspace-valid?</strong> <em>progspace</em></dt> |
| <dd><p>Return <code>#t</code> if <var>progspace</var> is valid, <code>#f</code> if not. |
| A <code><gdb:progspace></code> object can become invalid |
| if the program it refers to is not loaded in <small>GDB</small> any longer. |
| </p></dd></dl> |
| |
| <dl> |
| <dt><a name="index-current_002dprogspace"></a>Scheme Procedure: <strong>current-progspace</strong></dt> |
| <dd><p>This function returns the program space of the currently selected inferior. |
| There is always a current progspace, this never returns <code>#f</code>. |
| See <a href="Inferiors-and-Programs.html#Inferiors-and-Programs">Inferiors and Programs</a>. |
| </p></dd></dl> |
| |
| <dl> |
| <dt><a name="index-progspaces"></a>Scheme Procedure: <strong>progspaces</strong></dt> |
| <dd><p>Return a list of all the progspaces currently known to <small>GDB</small>. |
| </p></dd></dl> |
| |
| <dl> |
| <dt><a name="index-progspace_002dfilename"></a>Scheme Procedure: <strong>progspace-filename</strong> <em>progspace</em></dt> |
| <dd><p>Return the absolute file name of <var>progspace</var> as a string. |
| This is the name of the file passed as the argument to the <code>file</code> |
| or <code>symbol-file</code> commands. |
| If the program space does not have an associated file name, |
| then <code>#f</code> is returned. This occurs, for example, when <small>GDB</small> |
| is started without a program to debug. |
| </p> |
| <p>A <code>gdb:invalid-object-error</code> exception is thrown if <var>progspace</var> |
| is invalid. |
| </p></dd></dl> |
| |
| <dl> |
| <dt><a name="index-progspace_002dobjfiles"></a>Scheme Procedure: <strong>progspace-objfiles</strong> <em>progspace</em></dt> |
| <dd><p>Return the list of objfiles of <var>progspace</var>. |
| The order of objfiles in the result is arbitrary. |
| Each element is an object of type <code><gdb:objfile></code>. |
| See <a href="Objfiles-In-Guile.html#Objfiles-In-Guile">Objfiles In Guile</a>. |
| </p> |
| <p>A <code>gdb:invalid-object-error</code> exception is thrown if <var>progspace</var> |
| is invalid. |
| </p></dd></dl> |
| |
| <dl> |
| <dt><a name="index-progspace_002dpretty_002dprinters"></a>Scheme Procedure: <strong>progspace-pretty-printers</strong> <em>progspace</em></dt> |
| <dd><p>Return the list of pretty-printers of <var>progspace</var>. |
| Each element is an object of type <code><gdb:pretty-printer></code>. |
| See <a href="Guile-Pretty-Printing-API.html#Guile-Pretty-Printing-API">Guile Pretty Printing API</a>, for more information. |
| </p></dd></dl> |
| |
| <dl> |
| <dt><a name="index-set_002dprogspace_002dpretty_002dprinters_0021"></a>Scheme Procedure: <strong>set-progspace-pretty-printers!</strong> <em>progspace printer-list</em></dt> |
| <dd><p>Set the list of registered <code><gdb:pretty-printer></code> objects for |
| <var>progspace</var> to <var>printer-list</var>. |
| See <a href="Guile-Pretty-Printing-API.html#Guile-Pretty-Printing-API">Guile Pretty Printing API</a>, for more information. |
