tt_trace_control(library call)			tt_trace_control(library call)

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 control‐
       ling 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.

SEE ALSO
       Tt/tt_c.h - Tttt_c(5), ttsession(1).
