/**
|
||||
* Use this function to create a new SDL_RWops structure for reading from
|
||||
* and/or writing to a named file.
|
||||
*
|
||||
* The `mode` string is treated roughly the same as in a call to the C
|
||||
* library's fopen(), even if SDL doesn't happen to use fopen() behind the
|
||||
* scenes.
|
||||
*
|
||||
* Available `mode` strings:
|
||||
*
|
||||
* - "r": Open a file for reading. The file must exist.
|
||||
* - "w": Create an empty file for writing. If a file with the same name
|
||||
* already exists its content is erased and the file is treated as a new
|
||||
* empty file.
|
||||
* - "a": Append to a file. Writing operations append data at the end of the
|
||||
* file. The file is created if it does not exist.
|
||||
* - "r+": Open a file for update both reading and writing. The file must
|
||||
* exist.
|
||||
* - "w+": Create an empty file for both reading and writing. If a file with
|
||||
* the same name already exists its content is erased and the file is
|
||||
* treated as a new empty file.
|
||||
* - "a+": Open a file for reading and appending. All writing operations are
|
||||
* performed at the end of the file, protecting the previous content to be
|
||||
* overwritten. You can reposition (fseek, rewind) the internal pointer to
|
||||
* anywhere in the file for reading, but writing operations will move it
|
||||
* back to the end of file. The file is created if it does not exist.
|
||||
*
|
||||
* **NOTE**: In order to open a file as a binary file, a "b" character has to
|
||||
* be included in the `mode` string. This additional "b" character can either
|
||||
* be appended at the end of the string (thus making the following compound
|
||||
* modes: "rb", "wb", "ab", "r+b", "w+b", "a+b") or be inserted between the
|
||||
* letter and the "+" sign for the mixed modes ("rb+", "wb+", "ab+").
|
||||
* Additional characters may follow the sequence, although they should have no
|
||||
* effect. For example, "t" is sometimes appended to make explicit the file is
|
||||
* a text file.
|
||||
*
|
||||
* This function supports Unicode filenames, but they must be encoded in UTF-8
|
||||
* format, regardless of the underlying operating system.
|
||||
*
|
||||
* As a fallback, SDL_RWFromFile() will transparently open a matching filename
|
||||
* in an Android app's `assets`.
|
||||
*
|
||||
* Closing the SDL_RWops will close the file handle SDL is holding internally.

||||
* \param file a UTF-8 string representing the filename to open
