tt_trace_control(3)    C LIBRARY FUNCTIONS    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.

SEE ALSO
     Tttt_c(5),	ttsession(1).
