<p><a name="index-clearing-breakpoints_002c-watchpoints_002c-catchpoints-311"></a><a name="index-deleting-breakpoints_002c-watchpoints_002c-catchpoints-312"></a>It is often necessary to eliminate a breakpoint, watchpoint, or
|
|
catchpoint once it has done its job and you no longer want your program
|
|
to stop there. This is called <dfn>deleting</dfn> the breakpoint. A
|
|
breakpoint that has been deleted no longer exists; it is forgotten.
|
|
|
|
<p>With the <code>clear</code> command you can delete breakpoints according to
|
|
where they are in your program. With the <code>delete</code> command you can
|
|
delete individual breakpoints, watchpoints, or catchpoints by specifying
|
|
their breakpoint numbers.
|
|
|
|
<p>It is not necessary to delete a breakpoint to proceed past it. <span class="sc">gdb</span>
|
|
automatically ignores breakpoints on the first instruction to be executed
|
|
when you continue execution without changing the execution address.

|
|
<dl><dt><code>clear</code><dd>Delete any breakpoints at the next instruction to be executed in the
|
|
selected stack frame (see <a href="Selection.html#Selection">Selecting a Frame</a>). When
|
|
the innermost frame is selected, this is a good way to delete a
|
|
breakpoint where your program just stopped.
|
|

<br><dt><code>clear </code><var>location</var><dd>Delete any breakpoints set at the specified <var>location</var>.
|

See <a href="Specify-Location.html#Specify-Location">Specify Location</a>, for the various forms of <var>location</var>; the
|

most useful ones are listed below:
