Retrieve the address of one of the objects which can be accessed by the user functions
Synopsis
int XPRS_CC XSLPgetfuncobjectV(VARIANT *ArgInfo, int ObjType, void **Address)
Arguments
|
ArgInfo
|
The array of argument information for the user function.

Example
The following example retrieves the number of the function and the problem pointer. It then retrieves the internal name by which the function is known.
char fName[60];
int fNum;
XSLPprob Prob;
void *Object;
XSLPgetfuncinfoV(ArgInfo, NULL, NULL,
NULL, NULL, NULL, NULL,
&fNum, NULL);
XSLPgetfuncobjectV(ArgInfo, XSLP_XSLPPROBLEM, &Object);
Prob = (XSLPprob) Object;
XSLPgetnames(Prob, XSLP_USERFUNCNAMES, fName, fNum, fNum);
Further information
This function is identical to XSLPgetfuncobject except that ArgInfo is of type VARIANT rather than int. It is used in COM functions when the argument information array is passed as one of the arguments. To use this version of the function, pass the first member of array as the first argument to the function — e.g.
XSLPgetfuncobjectV(ArgInfo(0),......)
For functions which have no current instance because the function does not have instances, the Instance Function Object will be NULL.
For functions which have no current instance because the function was called directly from another user function, the Instance Function Object will be that set by the calling function.
