CPXXinfolongparam and CPXinfolongparam
The routine
CPXXinfolongparam/CPXinfolongparam
obtains the default, minimum, and maximum values of a CPLEX parameter of type
CPXLONG.
int CPXXinfolongparam( CPXCENVptr env, int whichparam, CPXLONG * defvalue_p, CPXLONG * minvalue_p, CPXLONG * maxvalue_p )
int CPXinfolongparam( CPXCENVptr env, int whichparam, CPXLONG * defvalue_p, CPXLONG * minvalue_p, CPXLONG * maxvalue_p )
Description
The routine CPXXinfolongparam/CPXinfolongparam obtains the default,
minimum, and maximum values of a CPLEX parameter of type
CPXLONG.
The CPLEX Parameters Reference Manual provides a list of parameters with their types, options, and default values.
Arguments
- env
-
A pointer to the CPLEX environment as returned by
CPXXopenCPLEX/CPXopenCPLEX. - whichparam
- The symbolic constant (or reference number) of the parameter for which the value is to be obtained.
- defvalue_p
- A pointer to an integer variable to hold the default value of the CPLEX parameter. May be NULL.
- minvalue_p
- A pointer to an integer variable to hold the minimum value of the CPLEX parameter. May be NULL.
- maxvalue_p
- A pointer to an integer variable to hold the maximum value of the CPLEX parameter. May be NULL.
Return
The routine returns 0 (zero) if successful and nonzero if an error occurs.Example
status = CPXinfolongparam (env, CPXPARAM_Simplex_Limits_Iterations,
&default_itlim,
&min_itlim,
&max_itlim);
CPX_PARAMTYPE_INT.
