GNU Info (gdb.info)Create and Delete TracepointsCreate and Delete Tracepoints ----------------------------- `trace' The `trace' command is very similar to the `break' command. Its argument can be a source line, a function name, or an address in the target program. Note: Set Breaks. The `trace' command defines a tracepoint, which is a point in the target program where the debugger will briefly stop, collect some data, and then allow the program to continue. Setting a tracepoint or changing its commands doesn't take effect until the next `tstart' command; thus, you cannot change the tracepoint attributes once a trace experiment is running. Here are some examples of using the `trace' command: (gdb) trace foo.c:121 // a source file and line number (gdb) trace +2 // 2 lines forward (gdb) trace my_function // first source line of function (gdb) trace *my_function // EXACT start address of function (gdb) trace *0x2117c4 // an address You can abbreviate `trace' as `tr'. The convenience variable `$tpnum' records the tracepoint number of the most recently set tracepoint. `delete tracepoint [NUM]' Permanently delete one or more tracepoints. With no argument, the default is to delete all tracepoints. Examples: (gdb) delete trace 1 2 3 // remove three tracepoints (gdb) delete trace // remove all tracepoints You can abbreviate this command as `del tr'. automatically generated by info2www version 1.2.2.9 |
