  67. <p><small>GDB</small> loads symbols for an inferior from various
  68. symbol-containing files (see <a href="Files.html#Files">Files</a>). These include the primary
  69. executable file, any shared libraries used by the inferior, and any
  70. separate debug info files (see <a href="Separate-Debug-Files.html#Separate-Debug-Files">Separate Debug Files</a>).
  71. <small>GDB</small> calls these symbol-containing files <em>objfiles</em>.
  72. </p>
  73. <p>Each objfile is represented as an object of type <code>&lt;gdb:objfile&gt;</code>.
  74. </p>
  75. <p>The following objfile-related procedures are provided by the

  86. A <code>&lt;gdb:objfile&gt;</code> object can become invalid
  87. if the object file it refers to is not loaded in <small>GDB</small> any
  88. longer. All other <code>&lt;gdb:objfile&gt;</code> procedures will throw an exception
