tt_trace_control − control client-side tracing

SYNOPSIS

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

The value of the onoff argument affects tracing as follows:

 0Tracing is turned off. 

 1Tracing is turned on. 

−1Tracing 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.
