101 | delete trace : delete one or more tracepoints. | |

105 | passcount : specify a pass count for a tracepoint. | |
106 | tstart : start a trace experiment. | |
107 | tstop : stop a trace experiment. | |
108 | tstatus : query the status of a trace experiment. | |
109 | tfind : find a trace frame in the trace buffer. | |
110 | tdump : print everything collected at the current tracepoint. | |
111 | save-tracepoints : write tracepoint setup into a file. | |
112 | ||
113 | This module defines the following user-visible debugger variables: | |
114 | $trace_frame : sequence number of trace frame currently being debugged. | |
115 | $trace_line : source line of trace frame currently being debugged. | |
116 | $trace_file : source file of trace frame currently being debugged. | |
117 | $tracepoint : tracepoint number of trace frame currently being debugged. | |
