| </pre> |
| <p>Set the passcount for tracepoint <var>tracepoint-number</var> to |
| <var>passcount</var>. If the breakpoint referred to by <var>tracepoint-number</var> |
| is not a tracepoint, error is emitted. This corresponds to CLI |
| command ‘<samp><span class="samp">passcount</span></samp>’. |

| |
| <h5 class="subsubheading">Synopsis</h5> |
| |
| <pre class="smallexample"> -break-watch [ -a | -r ] |
| </pre> |
| <p>Create a watchpoint. With the ‘<samp><span class="samp">-a</span></samp>’ option it will create an |
| <dfn>access</dfn> watchpoint, i.e., a watchpoint that triggers either on a |
| read from or on a write to the memory location. With the ‘<samp><span class="samp">-r</span></samp>’ |
| option, the watchpoint created is a <dfn>read</dfn> watchpoint, i.e., it will |
| trigger only when the memory location is accessed for reading. Without |
| either of the options, the watchpoint created is a regular watchpoint, |
| i.e., it will trigger when the memory location is accessed for writing. |
| See <a href="Set-Watchpoints.html#Set-Watchpoints">Setting Watchpoints</a>. |
| |
| <p>Note that ‘<samp><span class="samp">-break-list</span></samp>’ will report a single list of watchpoints and |
| breakpoints inserted. |
| |
| <h5 class="subsubheading"><span class="sc">gdb</span> Command</h5> |
| |
| <p>The corresponding <span class="sc">gdb</span> commands are ‘<samp><span class="samp">watch</span></samp>’, ‘<samp><span class="samp">awatch</span></samp>’, and |
| ‘<samp><span class="samp">rwatch</span></samp>’. |
| |
| <h5 class="subsubheading">Example</h5> |
| |
| <p>Setting a watchpoint on a variable in the <code>main</code> function: |
| |
| <pre class="smallexample"> (gdb) |
| -break-watch x |
| ^done,wpt={number="2",exp="x"} |
| (gdb) |
| -exec-continue |
| ^running |
| (gdb) |
| *stopped,reason="watchpoint-trigger",wpt={number="2",exp="x"}, |
| value={old="-268439212",new="55"}, |
| frame={func="main",args=[],file="recursive2.c", |
| fullname="/home/foo/bar/recursive2.c",line="5"} |
| (gdb) |
| </pre> |
| <p>Setting a watchpoint on a variable local to a function. <span class="sc">gdb</span> will stop |
| the program execution twice: first for the variable changing value, then |
| for the watchpoint going out of scope. |
