72
73<a name="index-progspaces-in-guile"></a>
74<a name="index-_003cgdb_003aprogspace_003e"></a>
75<p>A program space, or <em>progspace</em>, represents a symbolic view
76of an address space.
77It consists of all of the objfiles of the program.
78See <a href="Objfiles-In-Guile.html#Objfiles-In-Guile">Objfiles In Guile</a>.
79See <a href="Inferiors-Connections-and-Programs.html#Inferiors-Connections-and-Programs">program spaces</a>, for more details
80about program spaces.
81</p>
82<p>Each progspace is represented by an instance of the <code>&lt;gdb:progspace&gt;</code>
83smob.  See <a href="GDB-Scheme-Data-Types.html#GDB-Scheme-Data-Types">GDB Scheme Data Types</a>.
84</p>
85<p>The following progspace-related functions are available in the
86<code>(gdb)</code> module:
87</p>
88<dl>
89<dt><a name="index-progspace_003f"></a>Scheme Procedure: <strong>progspace?</strong> <em>object</em></dt>
90<dd><p>Return <code>#t</code> if <var>object</var> is a <code>&lt;gdb:progspace&gt;</code> object.
91Otherwise return <code>#f</code>.
92</p></dd></dl>
93
94<dl>
95<dt><a name="index-progspace_002dvalid_003f"></a>Scheme Procedure: <strong>progspace-valid?</strong> <em>progspace</em></dt>
96<dd><p>Return <code>#t</code> if <var>progspace</var> is valid, <code>#f</code> if not.
97A <code>&lt;gdb:progspace&gt;</code> object can become invalid
98if the program it refers to is not loaded in <small>GDB</small> any longer.
99</p></dd></dl>
100
101<dl>
102<dt><a name="index-current_002dprogspace"></a>Scheme Procedure: <strong>current-progspace</strong></dt>
103<dd><p>This function returns the program space of the currently selected inferior.
104There is always a current progspace, this never returns <code>#f</code>.
105See <a href="Inferiors-Connections-and-Programs.html#Inferiors-Connections-and-Programs">Inferiors Connections and Programs</a>.
106</p></dd></dl>
107
108<dl>
109<dt><a name="index-progspaces"></a>Scheme Procedure: <strong>progspaces</strong></dt>
110<dd><p>Return a list of all the progspaces currently known to <small>GDB</small>.
111</p></dd></dl>
112
113<dl>
114<dt><a name="index-progspace_002dfilename"></a>Scheme Procedure: <strong>progspace-filename</strong> <em>progspace</em></dt>
115<dd><p>Return the absolute file name of <var>progspace</var> as a string.
116This is the name of the file passed as the argument to the <code>file</code>
117or <code>symbol-file</code> commands.
118If the program space does not have an associated file name,
119then <code>#f</code> is returned.  This occurs, for example, when <small>GDB</small>
120is started without a program to debug.
121</p>
122<p>A <code>gdb:invalid-object-error</code> exception is thrown if <var>progspace</var>
123is invalid.
124</p></dd></dl>
125
126<dl>
127<dt><a name="index-progspace_002dobjfiles"></a>Scheme Procedure: <strong>progspace-objfiles</strong> <em>progspace</em></dt>
128<dd><p>Return the list of objfiles of <var>progspace</var>.
129The order of objfiles in the result is arbitrary.
130Each element is an object of type <code>&lt;gdb:objfile&gt;</code>.
131See <a href="Objfiles-In-Guile.html#Objfiles-In-Guile">Objfiles In Guile</a>.
132</p>
133<p>A <code>gdb:invalid-object-error</code> exception is thrown if <var>progspace</var>
134is invalid.
135</p></dd></dl>
136
137<dl>
138<dt><a name="index-progspace_002dpretty_002dprinters"></a>Scheme Procedure: <strong>progspace-pretty-printers</strong> <em>progspace</em></dt>
139<dd><p>Return the list of pretty-printers of <var>progspace</var>.
140Each element is an object of type <code>&lt;gdb:pretty-printer&gt;</code>.
141See <a href="Guile-Pretty-Printing-API.html#Guile-Pretty-Printing-API">Guile Pretty Printing API</a>, for more information.
142</p></dd></dl>
143
144<dl>
145<dt><a name="index-set_002dprogspace_002dpretty_002dprinters_0021"></a>Scheme Procedure: <strong>set-progspace-pretty-printers!</strong> <em>progspace printer-list</em></dt>
146<dd><p>Set the list of registered <code>&lt;gdb:pretty-printer&gt;</code> objects for
147<var>progspace</var> to <var>printer-list</var>.
148See <a href="Guile-Pretty-Printing-API.html#Guile-Pretty-Printing-API">Guile Pretty Printing API</a>, for more information.
