| <p><a name="index-Objective_002dC_002c-print-objects-1025"></a><a name="index-print_002dobject-1026"></a><a name="index-po-_0040r_007b_0028_0040code_007bprint_002dobject_007d_0029_007d-1027"></a> |
| The print command has also been extended to accept methods. For example: |
| |
| <pre class="smallexample"> print -[<var>object</var> hash] |
| </pre> |
| <p><a name="index-print-an-Objective_002dC-object-description-1028"></a><a name="index-g_t_0040code_007b_005fNSPrintForDebugger_007d_002c-and-printing-Objective_002dC-objects-1029"></a>will tell <span class="sc">gdb</span> to send the <code>hash</code> message to <var>object</var> |
| and print the result. Also, an additional command has been added, |
| <code>print-object</code> or <code>po</code> for short, which is meant to print |
| the description of an object. However, this command may only work |
| with certain Objective-C libraries that have a particular hook |
| function, <code>_NSPrintForDebugger</code>, defined. |
