13.2 Timing

The following routines involve "time marks," used as the basis for measuring performance characteristics of the system.

DXMarkTime()
void DXMarkTimeLocal();

Record the times of various events in system operation (e.g., the beginning and the end of module execution). Time marks are batched until DXPrintTimes() is called. See DXMarkTime, DXMarkTimeLocal.

void DXPrintTimes()

Prints time marks. The accumulation and printing of timing messages must be enabled by DXTraceTime(). See DXPrintTimes.

void DXTraceTime()

Enables or disables the accumulation of time marks. See DXTraceTime.

Note: For modules linked to Data Explorer, the Trace module enables the recording and printing of times (see Chapter 1. "Data Explorer Tools" in IBM Visualization Data Explorer User's Reference).

double DXGetTime()

Returns the elapsed time (in seconds) since system initialization. See DXGetTime.
