XPRBresetprob

Purpose

Release system resources used for storing solution information.

Synopsis

int XPRBresetprob(XPRBprob prob);

Argument

prob	Reference to a problem.

Return value

0 if function executed successfully, 1 otherwise.

Example

The following resets and frees resources used by BCL and Xpress-Optimizer for storing solution information:

XPRBprob expl2;
expl2 = XPRBnewprob(NULL):
 ...
XPRBsolve(expl2, "");
 ...
XPRBresetprob(expl2);

Further information

This function deletes any solution information stored in BCL; it also deletes the corresponding Xpress-Optimizer problem and removes any auxiliary files that may have been created by optimization runs. It also resets the Optimizer control parameters for spare matrix elements (EXTRACOLS, EXTRAROWS, and EXTRAELEMS) to their default values. The BCL problem definition itself remains. This function may be used to free up memory if the solution information is not required any longer but the problem definition is to be kept for later (re)use. To completely delete a problem the function XPRBdelprob needs to be used.
