## src_c/rwobject.c

This extension module implements functions for wrapping a Python file like object in a `SDL_RWops` struct for SDL file access.

Header file: src_c/include/pygame.h

SDL_RWops *pgRWops_FromObject(PyObject *obj)

  Return a SDL_RWops struct filled to access obj. If obj is a string then let SDL open the file it names. Otherwise, if obj is a Python file-like object then use its `read`, `write`, `seek`, `tell`, and `close` methods. If threads are available, the Python GIL is acquired before calling any of the obj methods. On error raise a Python exception and return `NULL`.

SDL_RWops *pgRWops_FromFileObject(PyObject *obj)

  Return a SDL_RWops struct filled to access the Python file-like object obj. Uses its `read`, `write`, `seek`, `tell`, and `close` methods. If threads are available, the Python GIL is acquired before calling any of the obj methods. On error raise a Python exception and return `NULL`.

int pgRWops_IsFileObject(SDL_RWops *rw)

  Return true if rw is a Python file-like object wrapper returned by `pgRWops_FromObject()` or `pgRWops_FromFileObject()`.

char *pgRWops_GetFileExtension(SDL_RWops *rw)

  Return a string that contains the file extension of the original file loaded into the SDL_RWops object, or NULL if the SDL_RWops object comes from a file object.

int pgRWops_ReleaseObject(SDL_RWops *context)

  Free a SDL_RWops struct. If it is attached to a Python file-like object, decrement its refcount. Otherwise, close the file handle. Return 0 on success. On error, raise a Python exception and return a negative value.

PyObject *pg_EncodeFilePath(PyObject *obj, PyObject *eclass)

  Return the file path obj as a byte string properly encoded for the OS. Null bytes are forbidden in the encoded file path. On error raise a Python exception and return `NULL`, using eclass as the exception type if it is not `NULL`. If obj is `NULL` assume an exception was already raised and pass it on.

PyObject *pg_EncodeString(PyObject *obj, const char *encoding, const char *errors, PyObject *eclass)

  Return string obj as an encoded byte string. The C string arguments encoding and errors are the same as for `PyUnicode_AsEncodedString()`. On error raise a Python exception and return `NULL`, using eclass as the exception type if it is not `NULL`. If obj is `NULL` assume an exception was already raised and pass it on.
