The problem is, that this code is very slow, compared to the speed of my SSD.

Stream.open('file.txt', std::fstream::in) Īnd this code for writing files: stream.write(file.str().data(), file.tellg()) Looking up C++ code and implementing some of the answers here for reading and writing files yielded me this code for reading a file: std::stringstream file There are two more things to do before you can use your new extension: compilingĪnd linking it with the Python system.I'm trying to read and write a few megabytes of data stored in files, consisting out of 8 floats converted to strings per line, to my SSD. PyInit_spam, and creation of the module is left to the import machinery.įor details on multi-phase initialization, see PEP 489. (new in Python 3.5), where a PyModuleDef structure is returned from Unlike our spam example, xxmodule uses multi-phase initialization Optionally followed by an import of the module: To add the module to the initialization table, use PyImport_AppendInittab(), When embedding Python, the PyInit_spam() function is not calledĪutomatically unless there’s an entry in the PyImport_Inittab table. So that it then gets inserted into sys.modules. The init function must return the module object to its caller, It may abort with a fatal error forĬertain errors, or return NULL if the module could not be initialized PyModule_Create() returns a pointer to the module object Table (an array of PyMethodDef structures) found in the module definition. Inserts built-in function objects into the newly created module based upon the It calls PyModule_Create(), which returns a module object, and (See below for comments about embedding Python.) When the Python program imports module spam for the first time, Note that PyMODINIT_FUNC declares the function as PyObject * return type,ĭeclares any special linkage declarations required by the platform, and for C++ Static PyObject * spam_system ( PyObject * self, PyObject * args )
