Define everything required for supporting a callback of type name. Use like so DEFINE_SCOPED_CB(CB_NAME, ORTOOLS_CB, CB_RET_TYPE, (...ARGS)) { } where CB_NAME is the name of the callback (Message, Checktime, ...) ORTOOLS_CB the Or-Tools callbacks (function object) that get provided to the low-level static callback as user data, and then invoked. CB_RET_TYPE return type of the low-level Xpress callback. (...ARGS) arguments to the Xpress low-level callback. code for the low-level Xpress callback The effect of the macro is an alias CB_NAME####ScopedCb = ScopedCallback<...>.
