|
|
<p><a name="index-progspaces-in-guile-2654"></a><a name="index-g_t_003cgdb_003aprogspace_003e-2655"></a>A program space, or <dfn>progspace</dfn>, 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>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>The following progspace-related functions are available in the
|
|
<code>(gdb)</code> module:
|
|
|
|
<div class="defun">
|
|
— Scheme Procedure: <b>progspace?</b><var> object<a name="index-progspace_003f-2656"></a></var><br>
|
|
<blockquote><p>Return <code>#t</code> if <var>object</var> is a <code><gdb:progspace></code> object.
|
|
Otherwise return <code>#f</code>.
|
|
</p></blockquote></div>
|
|
|
|
<div class="defun">
|
|
— Scheme Procedure: <b>progspace-valid?</b><var> progspace<a name="index-progspace_002dvalid_003f-2657"></a></var><br>
|
|
<blockquote><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 <span class="sc">gdb</span> any longer.
|
|
</p></blockquote></div>
|
|
|
|
<div class="defun">
|
|
— Scheme Procedure: <b>current-progspace</b><var><a name="index-current_002dprogspace-2658"></a></var><br>
|
|
<blockquote><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></blockquote></div>
|
|
|
|
<div class="defun">
|
|

<blockquote><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 <span class="sc">gdb</span>
|
|
is started without a program to debug.
|
|
|
|
<p>A <code>gdb:invalid-object-error</code> exception is thrown if <var>progspace</var>
|
|
is invalid.
