Query the values of a double-valued array attribute.
Return value:
A non-zero return value indicates that a problem occurred while querying the attribute. Refer to the Error Code table for a list of possible return values. Details on the error can be obtained by calling GRBgeterrormsg.
Arguments:
model: A loaded optimization model, typically created by routine GRBnewmodel or GRBreadmodel.
attrname: The name of a double-valued array attribute. Available attributes are listed and described in the Attributes section of this document.
len: The number of attribute elements to retrive.
ind: The indices of the desired attribute elements.
values: A pointer to the location where the requested attribute elements should be returned. Note that the result array must be as long as the requested index list.
Example usage:
int desired[] = {0, 2, 4, 6};
double x[4];
error = GRBgetdblattrlist(model, "X", 4, desired, cbasis);
