CPXXsetlongparam and CPXsetlongparam

The routine CPXXsetlongparam/CPXsetlongparam sets the value of a CPLEX parameter of type CPXLONG.

int  CPXXsetlongparam( CPXENVptr env, int whichparam, CPXLONG newvalue )

int  CPXsetlongparam( CPXENVptr env, int whichparam, CPXLONG newvalue )

Description

The routine CPXXsetlongparam/CPXsetlongparam sets the value 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 to change.
newvalue
The new value of the parameter.

Return

The routine returns 0 (zero) if successful and nonzero if an error occurs.

Example


status = CPXsetlongparam (env, CPXPARAM_Simplex_Limits_Iterations, 1000000000000LL);

Note:

It is technically possible but not recommended to call this routine for parameters of type CPX_PARAMTYPE_INT.
