 <span class="sc">gdb</span> represents every variable, function and type as an
 entry in a symbol table.  See <a href="Symbols.html#Symbols">Examining the Symbol Table</a>.
 Guile represents these symbols in <span class="sc">gdb</span> with the
 <code>&lt;gdb:symbol&gt;</code> object.

    <p>The following symbol-related procedures are provided by the
 <code>(gdb)</code> module:

 <div class="defun">

      <br><dt><code>SYMBOL_LOC_REGPARM_ADDR</code><a name="index-SYMBOL_005fLOC_005fREGPARM_005fADDR-2741"></a><dd>Value is a specified register.  Just like <code>LOC_REGISTER</code> except
 the register holds the address of the argument instead of the argument
 itself.

      <br><dt><code>SYMBOL_LOC_TYPEDEF</code><a name="index-SYMBOL_005fLOC_005fTYPEDEF-2743"></a><dd>Value not used.  Symbols in the domain <code>SYMBOL_STRUCT_DOMAIN</code> all

      <br><dt><code>SYMBOL_LOC_CONST_BYTES</code><a name="index-SYMBOL_005fLOC_005fCONST_005fBYTES-2745"></a><dd>Value is a byte-sequence.

      <br><dt><code>SYMBOL_LOC_UNRESOLVED</code><a name="index-SYMBOL_005fLOC_005fUNRESOLVED-2746"></a><dd>Value is at a fixed address, but the address of the variable has to be
 determined from the minimal symbol table whenever the variable is
 referenced.

      <br><dt><code>SYMBOL_LOC_OPTIMIZED_OUT</code><a name="index-SYMBOL_005fLOC_005fOPTIMIZED_005fOUT-2747"></a><dd>The value does not actually exist in the program.

      <br><dt><code>SYMBOL_LOC_COMPUTED</code><a name="index-SYMBOL_005fLOC_005fCOMPUTED-2748"></a><dd>The value's address is a computed location.

	<p>The available domain categories in <code><gdb:symbol></code> are represented

	<dl>
	<dt><code>SYMBOL_UNDEF_DOMAIN</code><a name="index-SYMBOL_005fUNDEF_005fDOMAIN-2728"></a><dd>This is used when a domain has not been discovered or none of the
	following domains apply. This usually indicates an error either
	in the symbol information or in <span class="sc">gdb</span>'s handling of symbols.

	<br><dt><code>SYMBOL_VAR_DOMAIN</code><a name="index-SYMBOL_005fVAR_005fDOMAIN-2729"></a><dd>This domain contains variables, function names, typedef names and enum
	type values.

	<br><dt><code>SYMBOL_STRUCT_DOMAIN</code><a name="index-SYMBOL_005fSTRUCT_005fDOMAIN-2730"></a><dd>This domain holds struct, union and enum type names.

	<br><dt><code>SYMBOL_LABEL_DOMAIN</code><a name="index-SYMBOL_005fLABEL_005fDOMAIN-2731"></a><dd>This domain contains names of labels (for gotos).

	<br><dt><code>SYMBOL_VARIABLES_DOMAIN</code><a name="index-SYMBOL_005fVARIABLES_005fDOMAIN-2732"></a><dd>This domain holds a subset of the <code>SYMBOLS_VAR_DOMAIN</code>; it
	contains everything minus functions and types.

	<br><dt><code>SYMBOL_FUNCTIONS_DOMAIN</code><a name="index-SYMBOL_005fFUNCTIONS_005fDOMAIN-2733"></a><dd>This domain contains all functions.

	<br><dt><code>SYMBOL_TYPES_DOMAIN</code><a name="index-SYMBOL_005fTYPES_005fDOMAIN-2734"></a><dd>This domain contains all types.
	</dl>

	<p>The available address class categories in <code><gdb:symbol></code> are represented
	as constants in the <code>gdb</code> module:

	<dl>
	<dt><code>SYMBOL_LOC_UNDEF</code><a name="index-SYMBOL_005fLOC_005fUNDEF-2735"></a><dd>If this is returned by address class, it indicates an error either in
	the symbol information or in <span class="sc">gdb</span>'s handling of symbols.

	<br><dt><code>SYMBOL_LOC_CONST</code><a name="index-SYMBOL_005fLOC_005fCONST-2736"></a><dd>Value is constant int.

	<br><dt><code>SYMBOL_LOC_STATIC</code><a name="index-SYMBOL_005fLOC_005fSTATIC-2737"></a><dd>Value is at a fixed address.

	<br><dt><code>SYMBOL_LOC_REGISTER</code><a name="index-SYMBOL_005fLOC_005fREGISTER-2738"></a><dd>Value is in a register.

	<br><dt><code>SYMBOL_LOC_ARG</code><a name="index-SYMBOL_005fLOC_005fARG-2739"></a><dd>Value is an argument. This value is at the offset stored within the
	symbol inside the frame's argument list.

	<br><dt><code>SYMBOL_LOC_REF_ARG</code><a name="index-SYMBOL_005fLOC_005fREF_005fARG-2740"></a><dd>Value address is stored in the frame's argument list. Just like
	<code>LOC_ARG</code> except that the value's address is stored at the
	offset, not the value itself.

	<br><dt><code>SYMBOL_LOC_REGPARM_ADDR</code><a name="index-SYMBOL_005fLOC_005fREGPARM_005fADDR-2741"></a><dd>Value is a specified register. Just like <code>LOC_REGISTER</code> except
	the register holds the address of the argument instead of the argument
	itself.

	<br><dt><code>SYMBOL_LOC_LOCAL</code><a name="index-SYMBOL_005fLOC_005fLOCAL-2742"></a><dd>Value is a local variable.

	<br><dt><code>SYMBOL_LOC_TYPEDEF</code><a name="index-SYMBOL_005fLOC_005fTYPEDEF-2743"></a><dd>Value not used. Symbols in the domain <code>SYMBOL_STRUCT_DOMAIN</code> all
	have this class.

	<br><dt><code>SYMBOL_LOC_BLOCK</code><a name="index-SYMBOL_005fLOC_005fBLOCK-2744"></a><dd>Value is a block.

	<br><dt><code>SYMBOL_LOC_CONST_BYTES</code><a name="index-SYMBOL_005fLOC_005fCONST_005fBYTES-2745"></a><dd>Value is a byte-sequence.

	<br><dt><code>SYMBOL_LOC_UNRESOLVED</code><a name="index-SYMBOL_005fLOC_005fUNRESOLVED-2746"></a><dd>Value is at a fixed address, but the address of the variable has to be
	determined from the minimal symbol table whenever the variable is
	referenced.

	<br><dt><code>SYMBOL_LOC_OPTIMIZED_OUT</code><a name="index-SYMBOL_005fLOC_005fOPTIMIZED_005fOUT-2747"></a><dd>The value does not actually exist in the program.

	<br><dt><code>SYMBOL_LOC_COMPUTED</code><a name="index-SYMBOL_005fLOC_005fCOMPUTED-2748"></a><dd>The value's address is a computed location.
