XSLPgetdtime

---

Purpose

Retrieve a double precision time stamp in seconds

Synopsis

int XPRS_CC XSLPgetdtime(XSLPprob Prob, double *Seconds);

Arguments

Prob	The current SLP problem.
Seconds	Address of double precision variable of the time in seconds.

Example

The following example measures the elapsed time to read a problem:

double Start, Finish;
XSLPgetdtime(Prob, &Start);
XSLPreadprob(Prob, "NewMat","");
XSLPgetdtime(Prob, &Finish);
printf("\nElapsed time to read = %lg secs",Finish-Start);

Further information

If Seconds is NULL, then the information will not be returned.

The timing information returned is provided by the operating system and is typically accurate to no more than 1 millisecond.

The clock is not initialized when Xpress-SLP starts, so it is necessary to save an initial time and then measure all times by difference.
