Purpose

Retrieve the value of a double precision problem attribute

Synopsis

int XPRS_CC XSLPgetdblattrib(XSLPprob Prob, int Param, double *dValue);

Arguments

Prob	The current SLP problem.
Param	attribute (SLP or optimizer) whose value is to be returned.
dValue	Address of a double precision variable to receive the value.

Example

The following example retrieves the value of the Xpress-SLP attribute XSLP_CURRENTDELTACOST and of the optimizer attribute XPRS_LPOBJVAL:

double DeltaCost, ObjVal;
XSLPgetdblattrib(Prob, XSLP_CURRENTDELTACOST, &DeltaCost);
XSLPgetdblattrib(Prob, XPRS_LPOBJVAL, &ObjVal);

Further information

Both SLP and optimizer attributes can be retrieved using this function. If an optimizer attribute is requested, the return value will be the same as that from XPRSgetdblattrib.
