Copy an existing model to a different environment. Multiple threads can not work simultaneously within the same environment. Copies of models must therefore reside in different environments for multiple threads to operate on them simultaneously.
Note that this method itself is not thread safe, so you should either call it from the main thread or protect access to it with a lock.
Note that pending updates will not be applied to the model, so you should call GRBupdatemodel before copying if you would like those to be included in the copy.
For Compute Server users, note that you can copy a model from a client to a Compute Server environment, but it is not possible to copy models from a Compute Server environment to another (client or Compute Server) environment.
A non-zero return value indicates that a problem occurred while copying the model. Refer to the Error Code table for a list of possible return values. Details on the error can be obtained by calling GRBgeterrormsg.
model: The model to copy.
targetenv: The environment to copy the model into.
resultP: The resulting model copy.
error = GRBcopymodeltoenv(orig, env2, ©);
