int GRBgetstrparam ( GRBenv *env,
    const char *paramname,
    char *value )

Retrieve the value of a string-valued parameter.

Note that a model gets its own copy of the environment when it is created. Changes to the original environment have no effect on the copy, and vice versa. Use GRBgetenv to retrieve the environment associated with a model if you would like to query the parameter value for that model.

Return value:

A non-zero return value indicates that a problem occurred while retrieving the parameter. Refer to the Error Code table for a list of possible return values. Details on the error can be obtained by calling GRBgeterrormsg.


env: The environment whose parameter value is being queried.

paramname: The name of the parameter. Please consult the parameter section for a complete list of Gurobi parameters, including descriptions of their purposes and their minimum, maximum, and default values.

value: The location in which the current value of the requested parameter should be placed.

Example usage:

  char logfilename[GRB_MAX_STRLEN];
  error = GRBgetstrparam(GRBgetenv(model), "LogFile", logfilename);
