tt_trace_control(3)

NAME
     tt_trace_control - control client-side tracing

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

DESCRIPTION
     The tt_trace_control() function sets or clears an internal flag
     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
     flag.

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