| <dl><dt><code>info static-tracepoint-markers</code><dd>Display information about all static tracepoint markers defined in the |
| program. |
| |
| <p>For each marker, the following columns are printed: |
| |
| <dl> |
| <dt><em>Count</em><dd>An incrementing counter, output to help readability. This is not a |
| stable identifier. |
| <br><dt><em>ID</em><dd>The marker ID, as reported by the target. |
| <br><dt><em>Enabled or Disabled</em><dd>Probed markers are tagged with ‘<samp><span class="samp">y</span></samp>’. ‘<samp><span class="samp">n</span></samp>’ identifies marks |
| that are not enabled. |
| <br><dt><em>Address</em><dd>Where the marker is in your program, as a memory address. |
| <br><dt><em>What</em><dd>Where the marker is in the source for your program, as a file and line |
| number. If the debug information included in the program does not |
| allow <span class="sc">gdb</span> to locate the source of the marker, this column |
| will be left blank. |
| </dl> |
| |
| <p class="noindent">In addition, the following information may be printed for each marker: |
| |
| <dl> |
| <dt><em>Data</em><dd>User data passed to the tracing library by the marker call. In the |
| UST backend, this is the format string passed as argument to the |
| marker call. |
| <br><dt><em>Static tracepoints probing the marker</em><dd>The list of static tracepoints attached to the marker. |
