XSLPgetdtime
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 NonLinear starts, so it is necessary to save an initial time and then measure all times by difference.
