Purpose
Set or define one of the objects which can be accessed by the user functions
Synopsis
int XPRS_CC XSLPsetuserfuncobject(XSLPprob Prob, int Entity, void *Address);
Arguments
|
Prob
|
The current SLP problem.
|
|
Entity
|
An integer indicating which object is to be defined. The value is
interpreted as follows:
|
0
|
The Global Function Object;
|
|
n > 0
|
The User Function Object for user function number n;
|
|
n < 0
|
The Instance Function Object for user function instance
number -n.
|
|
|
Address
|
The address of the object.
|
Example
The following example sets the Global Function Object. It then
sets the User Function Object for the function ProfitCalcs.
double *GlobObj;
void *ProfitObj;
int iUF;
XSLPsetuserfuncobject(Prob, 0, GlobObj);
if (!XSLPgetindex(Prob, XSLP_USERFUNCNAMESNOCASE,
"ProfitCalcs", &iUF)) {
XSLPsetuserfuncobject(Prob, iUF, ProfitObj);
}The function objects can be of any type. The index of the user function is
obtained using the case-insensitive search for names. If the name is not found,
XSLPgetindex returns a nonzero value.
Further information
As instance numbers are not normally meaningful, this function should only
be used with a negative value of n to reset all Instance Function Objects
to NULL when a model is being re-optimized within the same program execution.
