CPXinfodblparam

int CPXPUBLIC CPXinfodblparam(CPXCENVptr env, int whichparam, double * defvalue_p, double * minvalue_p, double * maxvalue_p)

Definition file: cplex.h

The routine CPXinfodblparam is used to obtain the default, minimum, and maximum values of a CPLEX parameter of type double.

Note

Values of zero obtained for both the minimum and maximum values of a parameter of type double indicate that the parameter has no limit.

The reference manual ILOG CPLEX Parameters, provides a list of parameters with their types, options, and default values.

Example

 status = CPXinfodblparam (env, CPX_PARAM_TILIM, &default_tilim,
                           &min_tilim, &max_tilim);

env	A pointer to the CPLEX environment as returned by `CPXopenCPLEX`.
whichparam	The symbolic constant (or reference number) of the parameter value to be obtained.
defvalue_p	A pointer to a variable of type `double` to hold the default value of the CPLEX parameter. May be NULL.
minvalue_p	A pointer to a variable of type `double` to hold the minimum value of the CPLEX parameter. May be NULL.
maxvalue_p	A pointer to a variable of type `double` to hold the maximum value of the CPLEX parameter. May be NULL.

The routine returns zero on success and nonzero if an error occurs.
