GNU Info (gdb.info)Tracepoint VariablesConvenience Variables for Tracepoints ===================================== `(int) $trace_frame' The current trace snapshot (a.k.a. "frame") number, or -1 if no snapshot is selected. `(int) $tracepoint' The tracepoint for the current trace snapshot. `(int) $trace_line' The line number for the current trace snapshot. `(char []) $trace_file' The source file for the current trace snapshot. `(char []) $trace_func' The name of the function containing `$tracepoint'. Note: `$trace_file' is not suitable for use in `printf', use `output' instead. Here's a simple example of using these convenience variables for stepping through all the trace snapshots and printing some of their data. (gdb) tfind start (gdb) while $trace_frame != -1 > output $trace_file > printf ", line %d (tracepoint #%d)\n", $trace_line, $tracepoint > tfind > end automatically generated by info2www version 1.2.2.9 |
