Given a subprogram call in which +the function symbol has multiple definitions, it will use the number of +actual parameters and some information about their types to attempt to narrow +the set of definitions. It also makes very limited use of context, preferring +procedures to functions in the context of the <code>call</code> command, and +functions to procedures elsewhere. +</p> +<p>If, after narrowing, the set of matching definitions still contains more than +one definition, <small>GDB</small> will display a menu to query which one it should +use, for instance: +</p> +<div class="smallexample"> +<pre class="smallexample">(gdb) print f(1) +Multiple matches for f +[0] cancel +[1] foo.f (integer) return boolean at foo.adb:23 +[2] foo.f (foo.new_integer) return boolean at foo.adb:28 +> +</pre></div> + +<p>In this case, just select one menu entry either to cancel expression evaluation +(type <kbd>0</kbd> and press <tt class="key">RET</tt>) or to continue evaluation with a specific +instance (type the corresponding number and press <tt class="key">RET</tt>). +</p> +<p>Here are a couple of commands to customize <small>GDB</small>’s behavior in this +case: +</p> +<dl compact="compact"> +<dd> +<a name="index-set-ada-print_002dsignatures"></a> +</dd> +<dt><code>set ada print-signatures</code></dt> +<dd><p>Control whether parameter types and return types are displayed in overloads +selection menus.
