tcl_procflow_example.txt

The following are examples of tcl_procflow.d.

This is a simple script to trace the flow of Tcl procedures.

Here it traces the example program, Code/Tcl/func_abc.tcl.

# tcl_procflow.d
  C    PID TIME(us)         -- PROCEDURE
  0  16073 3904971507502    -> tclInit
  0  16073 3904971509096    <- tclInit
  0  16073 3904971509305    -> func_a
  0  16073 3904972511039      -> func_b
  0  16073 3904973521023        -> func_c
  0  16073 3904974530998        <- func_c
  0  16073 3904974531008      <- func_b
  0  16073 3904974531014    <- func_a
^C

As each procedure starts, the third column is indented by 2 spaces. This
shows which procedure is calling which - the output above begins with an init
procedure and then shows that func_a began, and then called func_b.

The columns are CPU, PID, Time since boot, indicator and procedure name.

If the output looks shuffled, check the CPU "C" and "TIME" columns, and
post sort based on TIME if necessary.

See Notes/ALLflow_notes.txt for important notes about reading flow outputs.
