The routine CPXgetchgparam
returns an arrary of
parameter numbers (unique identifiers) for parameters which are
not set at their default values.
env | A pointer to the CPLEX environment, as returned by |
cnt_p | A pointer to an integer to contain the number of parameter numbers (unique identifiers) returned, that is, the true length of the array |
paramnum | The array to contain the numbers of the parameters with nondefault values. |
pspace | An integer specifying the length of the array |
surplus_p | A pointer to an integer to contain the difference between |
The routine returns zero if successful and nonzero if an error
occurs. The value CPXERR_NEGATIVE_SURPLUS
specifies that
insufficient space was available in the array paramnum
to hold the parameter numbers (unique identifiers) with nondefault values.
