File Objects

In Python 3, files and streams use the new io module, which defines several layers over the low-level unbuffered I/O of the operating system. The functions described below are convenience C wrappers over these new APIs, and meant mostly for internal error reporting in the interpreter; third-party code is advised to access the io APIs instead

• PyObject *PyFile_FromFd(int fd, const char *name, const char *mode, int buffering, const char *encoding, const char *errors, const char *newline, int closefd)
• int PyObject_AsFileDescriptor(PyObject *p)
• PyObject *PyFile_GetLine(PyObject *p, int n)
• int PyFile_SetOpenCodeHook(Py_OpenCodeHookFunction handler)
• int PyFile_WriteObject(PyObject *obj, PyObject *p, int flags)
• int PyFile_WriteString(const char *s, PyObject *p)
