|
||
|
|
<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.
