GRBModel::write()

This method is the general entry point for writing model data to a file. It can be used to write optimization models, IIS submodels, solutions, basis vectors, MIP start vectors, or parameter settings. The type of file written is determined by the file suffix. File formats are described in the File Format section.

Note that writing a model to a file will process all pending model modifications. However, writing other model information (solutions, bases, etc.) will not.
