returns the number of integer variables in the problem.
Returns
A zero value if the function terminated correctly, and a non-zero value if an error occurred.
Description
This function can be used to obtain the number of integer variables in the problem, that is, the number of variables that are required to take on integer values.
Example
/* p is an initialized QSprob, a handle to an existing LP problem */
int rval, count;
rval = QSget_intcount (p, &count);
if (rval) {
fprintf (stderr,
"could not get integer count, error code %d\n", rval);
} else {
printf ("Problem has %d integer variables\n", count);
}
