| symbol-containing files (see <a href="Files.html#Files">Files</a>). These include the primary |
| executable file, any shared libraries used by the inferior, and any |
| separate debug info files (see <a href="Separate-Debug-Files.html#Separate-Debug-Files">Separate Debug Files</a>). |
| <span class="sc">gdb</span> calls these symbol-containing files <dfn>objfiles</dfn>. |

| <p>Each objfile is represented as an object of type <code><gdb:objfile></code>. |

| <blockquote><p>Return <code>#t</code> if <var>object</var> is a <code><gdb:objfile></code> object. |

| A <code><gdb:objfile></code> object can become invalid |
| if the object file it refers to is not loaded in <span class="sc">gdb</span> any |
| longer. All other <code><gdb:objfile></code> procedures will throw an exception |
| if it is invalid at the time the procedure is called. |
