|
<p>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 <em>deleting</em> the breakpoint. A
|
breakpoint that has been deleted no longer exists; it is forgotten.
|
</p>
|
<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>
|
<p>It is not necessary to delete a breakpoint to proceed past it. <small>GDB</small>
|
automatically ignores breakpoints on the first instruction to be executed
|
when you continue execution without changing the execution address.

<dd><p>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.
