XSLPgettime

---

Purpose

Retrieve an integer time stamp in seconds and/or milliseconds

Synopsis

int XPRS_CC XSLPgettime(XSLPprob Prob, int *Seconds, int *MSeconds);

Arguments

Prob	The current SLP problem.
Seconds	Address of integer to receive the number of seconds.
MSeconds	Address of integer to receive the number of milliseconds. May be NULL if not required.

Example

The following example prints the time elapsed in milliseconds for reading a matrix.

int Secs, MSecs, StartSecs, StartMSecs, Elapsed;
XSLPgettime(Prob, &StartSecs, &StartMSecs);
XSLPreadprob(Prob, "Matrix", "");
XSLPgettime(Prob, &Secs, &MSecs);

Elapsed = (Secs-StartSecs)*1000
          + (MSecs - StartMSecs);
printf("\nElapsed time = %d",Elapsed);

Further information

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

This routine relies on the accuracy of the system clock.

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.
