[issue15948] Unchecked return value of I/O functions

[Christian Heimes]

Christian Heimes added the comment:

The functions should set an appropriate errno so it's PyErr_SetFromErrno(PyExc_IOError). You should use the PyErr_SetFromErrnoWithFilename*() variants when a file name (PyObject*, char*, unicode) is available.
