XPRSgetintattrib, XPRSgetintattrib64

Purpose

Enables users to recover the values of various integer problem attributes. Problem attributes are set during loading and optimization of a problem.

Synopsis

int XPRS_CC XPRSgetintattrib(XPRSprob prob, int ipar, int *ival);

int XPRS_CC XPRSgetintattrib64(XPRSprob prob, int ipar, XPRSint64 *ival);

Arguments

prob	The current problem.
ipar	Problem attribute whose value is to be returned. A full list of all problem attributes may be found in Chapter Problem Attributes, or from the list in the xprs.h header file.
ival	Pointer to an integer where the value of the problem attribute will be returned.

Example

The following obtains the number of columns in the matrix and allocates space to obtain lower bounds for each column:

int cols;
double *lb;
...
XPRSgetintattrib(prob,XPRS_COLS,&cols);
lb = (double *) malloc(sizeof(double)*cols);
XPRSgetlb(prob,lb,0,cols-1);
