| <p><a name="index-clearing-breakpoints_002c-watchpoints_002c-catchpoints-262"></a><a name="index-deleting-breakpoints_002c-watchpoints_002c-catchpoints-263"></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. |
| |
| |
| <a name="index-clear-264"></a> |
| <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: |
| |
| <dl> |
| <dt><code>clear </code><var>function</var><dt><code>clear </code><var>filename</var><code>:</code><var>function</var><dd>Delete any breakpoints set at entry to the named <var>function</var>. |
| |
| <br><dt><code>clear </code><var>linenum</var><dt><code>clear </code><var>filename</var><code>:</code><var>linenum</var><dd>Delete any breakpoints set at or within the code of the specified |
| <var>linenum</var> of the specified <var>filename</var>. |
| </dl> |

| ranges specified as arguments. If no argument is specified, delete all |
| breakpoints (<span class="sc">gdb</span> asks confirmation, unless you have <code>set |
