      1 The following are examples of tcl_procflow.d.
      2 
      3 This is a simple script to trace the flow of Tcl procedures.
      4 
      5 Here it traces the example program, Code/Tcl/func_abc.tcl.
      6 
      7 # tcl_procflow.d
      8   C    PID TIME(us)         -- PROCEDURE
      9   0  16073 3904971507502    -> tclInit
     10   0  16073 3904971509096    <- tclInit
     11   0  16073 3904971509305    -> func_a
     12   0  16073 3904972511039      -> func_b
     13   0  16073 3904973521023        -> func_c
     14   0  16073 3904974530998        <- func_c
     15   0  16073 3904974531008      <- func_b
     16   0  16073 3904974531014    <- func_a
     17 ^C
     18 
     19 As each procedure starts, the third column is indented by 2 spaces. This
     20 shows which procedure is calling which - the output above begins with an init
     21 procedure and then shows that func_a began, and then called func_b.
     22 
     23 The columns are CPU, PID, Time since boot, indicator and procedure name.
     24 
     25 If the output looks shuffled, check the CPU "C" and "TIME" columns, and
     26 post sort based on TIME if necessary.
