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:

    Tracing is turned off. Tracing is turned on. 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.
