tt_trace_control(3)


CDE


NAME

  tt_trace_control - control client-side tracing


SYNOPSIS

  #include <tt_c.h>
  int tt_trace_control(int onoff);


DESCRIPTION

  The tt_trace_control function sets or clears an internal option controlling
  all client-side tracing. The intent of this is to be called from debugger
  breakpoints, allowing a programmer to narrow the trace to the suspect area.

  The value of the onoff argument affects tracing as follows:

   0  Tracing is turned off.

   1  Tracing is turned on.

  -1  Tracing is turned on if it was off and vice-versa.


RETURN VALUE

  The tt_trace_control function returns the previous setting of the trace
  option.


APPLICATION USAGE

  This call does not return one of the TT_xxx type of errors or warnings, but
  only the numbers 1 or zero.
